Only One Earth: 4 Ways Nuclear Science is Helping the Environment

Today is World Environment Day, the international day calling for collective, transformative action on a global scale to celebrate, protect, and restore our planet. For too long human activities have over extracted from and polluted natural environments, and the consequences have been dire: out-of-control climate change, massive biodiversity loss, the emergence and spread of new diseases. However, hope is not lost and solutions exists that can remedy the damage caused and set our planet on a path towards recovery — some of these solutions rely on nuclear science.

Here are just four ways in which nuclear science and technology is playing an important role in protecting, conserving, and restoring our environment.

1. Mitigating climate change

Climate change is one of the biggest challenges facing humanity and it’s driven — to a great extent — by carbon emissions from burning fossil fuels. Reducing and ultimately ending these emissions requires an enormous, concerted effort by governments, industry and citizens to cut our reliance on fossil fuels and transition to low-carbon energy sources such as renewables and nuclear power.

Nuclear power accounts for roughly 10 per cent of the world’s electricity and over a quarter of its low-carbon electricity. When generating electricity, a nuclear power plant produces almost no carbon emissions — listen to our podcast to find out more — and so can play a key role in the transition to a low-emission energy future. The IAEA supports countries pursuing nuclear power programmes and has produced a trove of knowledge on how nuclear power can contribute towards decarbonisation and timely climate action. Recently, the IAEA launched an initiative to fast-track the development of hydrogen from nuclear to help decarbonise the most challenging fossil fuel-reliant sectors, such as heavy industry and transport.

2. Recycling plastic pollution

Since 1950, over eight billion tonnes of plastic have been produced. Plastic pollution has become one of today’s most pressing global environmental challenges, both on land and at sea where it chokes animals and seabirds and has begun to enter food webs. Not nearly enough of plastic is recycled or can be recycled using conventional methods, so the IAEA is working with countries to find solutions with the help of radiation technologies.

Last year the IAEA launched NUTEC Plastics, an initiative that supports using specialized nuclear methods to precisely track and quantify the movement and impacts of microplastic particles and associated co-contaminants in the environment — allowing experts to determine the status and trends of marine plastics, assess their impact on marine animals, and develop risk scenarios for informed decision making.

The initiative is also helping to make more plastics recyclable. Using radiation processes such as cross-linking, chain scission, grafting and other surface modifications, experts can help turn previously unrecyclable plastics into recyclable ones. Check out our recent photo essay on using irradiation towards a circular economy too learn more about the use of this technology in the Philippines.

3. Monitoring environmental pollution

Many activities in the modern world release pollutants into the environment. Pollution in the air, water, or soil impact and become a part of biological, geological and chemical cycles. Using nuclear techniques and tools, experts can study these processes to deal with pollutants and contaminated sites.

In the air, isotopic and nuclear tools are used monitor the pathways of heavy metal, greenhouse gases, and radioactive gases and particles through the atmosphere. Here’s a video on how scientists are able to use stable isotopes to ‘fingerprint’ greenhouse gases present in a sample of air and trace it to its source.

On land, nuclear techniques can precisely identify and measure pollutants. Using such techniques, the IAEA assists countries with monitoring, modelling and assessments for environmental protection initiatives. Here’s an example of how the IAEA has trained scientists and experts from Africa in correctly collecting and pre-treating environmental samples for measurement of radioactivity.

At sea, cutting-edge nuclear and isotopic techniques can accurately monitor pollution, minimise the impact of incidents and mitigate their effect on local populations. In January, Peru experienced a major oil spill because of a tsunami from a distant earthquake in Tonga, and the IAEA sent a fact-finding expert mission to support the country’s efforts to clean up the spill and monitor its effects.

4. Managing freshwater resources

Human life depends on the availability of water. Making sure the water we extract for drinking, industry and agriculture is sustainable can be achieved by measuring ratios of isotopes in the water — a field of science called isotope hydrology.

The IAEA support countries through its isotope hydrology laboratory with the application of nuclear and isotopic techniques in all aspects of freshwater resource assessments and water management and protection. For example, in Zimbabwe the IAEA is helping experts use isotopic techniques to assess the interactions of their groundwater and river systems, so as to better manage their freshwater resources, cope with pollution, and ensure safe water supplies for people. In Bolivia, nuclear techniques are being used to monitor glacier retreat and the impact it has on wetlands.

Multi-country monkeypox outbreak: Situation Update (4 June 2022)

The current publication of Disease Outbreak News is an update to the previously published Disease Outbreak News of 29 May and also provides short summaries of guidance, including on vaccination.

Outbreak at a glance

Since 13 May 2022, and as of 2 June 2022, 780 laboratory confirmed cases of monkeypox have been reported to or identified by WHO from 27 Member States across four WHO regions that are not endemic for monkeypox virus. Epidemiological investigations are ongoing. Most reported cases so far have been presented through sexual health or other health services in primary or secondary health care facilities and have involved mainly, but not exclusively, men who have sex with men (MSM).

While the West African clade of the virus has been identified from samples of cases so far, most confirmed cases with travel history reported travel to countries in Europe and North America, rather than West or Central Africa where the monkeypox virus is endemic. The confirmation of monkeypox in persons who have not travelled to an endemic area is atypical, and even one case of monkeypox in a non-endemic country is considered an outbreak. While most cases are not associated with travel from endemic areas, Member States are also reporting small numbers of cases in travelers from Nigeria, as has been observed before.

The sudden and unexpected appearance of monkeypox simultaneously in several non-endemic countries suggests that there might have been undetected transmission for some unknown duration of time followed by recent amplifier events.

WHO assesses the risk at the global level as moderate considering this is the first time that many monkeypox cases and clusters are reported concurrently in non-endemic and endemic countries in widely disparate WHO geographical areas.

WHO continues to receive updates on the situation in endemic countries.

Description of the outbreak

As of 2 June 2022, 780 laboratory confirmed cases have been notified to WHO under the International Health Regulations (IHR) or identified by WHO from official public sources in 27 non-endemic countries in four WHO Regions. This represents an increase of 523 laboratory confirmed cases (+203%) since the Disease Outbreak News of 29 May, when a total of 257 cases were reported. As of 2 June 2022, there have been no deaths associated within the current monkeypox outbreak in non-endemic countries, however, cases and deaths continue to be reported from endemic countries (see Table 2).

While investigations are ongoing, preliminary data from polymerase chain reaction (PCR) assays indicate that the monkeypox virus strains detected in Europe and other non-endemic areas belong to the West African clade.

Figure 1 and Table 1 show the geographical distribution of monkeypox cases reported to or identified by WHO between 13 May to 2 June 2022 in non-endemic countries. The majority of cases (n=688; 88%), were reported from the WHO European Region (20 Countries). Confirmed cases have also been reported from the Region of the Americas (n=80; 10%), Eastern Mediterranean Region (n=9; 1%) and Western Pacific Region (n=3; <1%).

The case count fluctuates as more information becomes available daily and data is verified by WHO in accordance with the provisions of the IHR.

To date, the clinical presentation of confirmed cases has been variable. Many cases in this outbreak are not presenting with the classical clinical picture for monkeypox. In cases described thus far in this outbreak, common presenting symptoms include genital and peri-anal lesions, fever, swollen lymph nodes, and pain when swallowing. While oral sores remain a common feature in combination with fever and swollen lymph nodes, the local anogenital distribution of rash (with vesicular, pustular or ulcerated lesions) sometimes appears first without consistently spreading to other parts of the body. This initial presentation of a genital or peri-anal rash in many cases suggests close physical contact as the likely route of transmission during sexual contact. Some cases have also been described as having pustules appear before constitutional symptoms (e.g., fever) and having lesions at different stages of development, both of which are atypical of how monkeypox has presented historically. Apart from patients hospitalized for the purpose of isolation, few hospitalizations have been reported. Complications leading to hospitalization have included the need to provide adequate pain management and the need to treat secondary infections.

In addition to the cases reported from or identified in non-endemic countries, WHO continues to receive updates on the status of ongoing monkeypox outbreaks in endemic countries^[1]^ in the African region through established surveillance mechanisms (Integrated Disease Surveillance and Response). From January to 1 June 2022, 1408 suspected and 44 confirmed cases including 66 deaths were reported from seven endemic countries (Table 2).

^[1]^ Monkeypox endemic countries are: Cameroon, the Central African Republic, the Democratic Republic of the Congo, Gabon, Ghana (identified in animals only), Cote d’Ivoire, Liberia, Nigeria, the Republic of the Congo, and Sierra Leone. Benin and South Sudan have documented importations in the past. Countries currently reporting cases of the West African clade are Cameroon and Nigeria.

The situation is evolving and WHO expects that there will be more cases of monkeypox identified as the outbreak progresses and as surveillance expands in both endemic and non-endemic countries.

Public health response

WHO continues to support sharing of information about this outbreak of monkeypox. Clinical and public health incident response has been activated at WHO and in many Member States to coordinate comprehensive case finding, contact tracing, laboratory investigation, clinical management, isolation, and implementation of infection and prevention and control measures.

Genomic sequencing of viral deoxyribonucleic acid (DNA) of the monkeypox virus, where available, is being undertaken. Several European countries (Belgium, France, Germany, Israel, Italy, the Netherlands, Portugal, Slovenia, Spain, Switzerland and the United States of America) have published full-length or partial genome sequences of the monkeypox virus found in the current outbreak. While investigations are ongoing, preliminary data from PCR assays indicate that the monkeypox virus genes detected belong to the West African clade.

ACAM-2000 and MVA-BN vaccines are being deployed by some Member States to manage close contacts. Others may hold supplies of LC16 vaccines.

Interim guidance is being developed to support Member States with surveillance, laboratory diagnostics and testing, case investigation and contact tracing, clinical management, vaccines and immunization, and risk communication and community engagement.

WHO has updated its guidance on monkeypox outbreak response and published the following documents:

WHO interim guidance on the clinical management and infection prevention and control for monkeypox, and on vaccines and immunization for monkeypox, will be published shortly.

WHO risk assessment

Currently, the public health risk at the global level is assessed as moderate considering this is the first time that many monkeypox cases and clusters are reported concurrently in non-endemic and endemic countries in widely disparate WHO geographical areas.

Cases were initially and mainly identified amongst men self-identified as part of extended sexual networks. The sudden appearance and wide geographic scope of many cases that initially appeared to be sporadic cases indicate that extended human-to-human transmission was facilitated by frequent encounters between persons in close proximity and/or with physical contact. Some countries are reporting that new generations of cases are no longer appearing only among known contacts of previously confirmed cases, suggesting that chains of transmission are being missed through undetected circulation of the virus.

Additionally, as epidemiological and laboratory information are still limited, the actual number of cases is likely an underestimate. This may in part be due to the lack of early clinical recognition of an infection previously known to occur mostly in West and Central Africa, limited surveillance, and a lack of widely available diagnostics in some countries. Given the number of countries across several WHO regions reporting cases of monkeypox, it is highly likely that other countries will identify cases and there will be further spread of the virus.

Human-to-human transmission occurs through close proximity or direct physical contact (e.g., face-to-face, skin-to-skin, mouth-to-mouth, mouth-to-skin contact including during sex) with skin or mucous membranes that may have recognized or unrecognized infectious lesions such as mucocutaneous ulcers, respiratory droplets (and possibly short-range aerosols), or contact with contaminated materials (e.g., linens, bedding, electronics, clothing).

Although the current risk to human health and for the general public remains low, the public health risk could become high if this virus exploits the opportunity to establish itself in non-endemic countries as a widespread human pathogen. There is also a risk to health workers if they are not using adequate infection prevention and control (IPC) measures or wearing appropriate personal protective equipment (PPE) when necessary, to prevent transmission. Though not reported in this current outbreak, the risk of health care associated infections has been documented in the past in both endemic and non-endemic areas. There is the potential for increased health impact with wider dissemination in vulnerable groups, as the risk of severe disease and mortality is recognized to be higher among children and immunocompromised individuals. There is limited data among people living with HIV, but those who take antiretrovirals and have a robust immune system have not reported a more severe course; those people living with HIV who are not on treatment or remain immunosuppressed may have a more severe course, as documented in the literature. Infection with monkeypox in pregnancy is poorly understood, although limited data suggest that infection may lead to adverse outcomes for the foetus.

To date, all cases identified in non-endemic countries whose samples were confirmed by PCR have been identified as being infected with the West African clade. There are two known clades of monkeypox, one endemic to West Africa (WA) and one to the Congo Basin (CB) region. The WA clade has in the past been associated with an overall lower mortality rate of <3% while the CB clade appears to more frequently cause severe disease with a case fatality ratio (CFR) previously reported from 1-10%; both estimates are based on infections among a generally younger population in the African setting.

Vaccination against smallpox had been shown to be cross-protective against monkeypox. However, immunity from smallpox vaccination will be limited to persons under the age of 40 or 50 years since smallpox vaccination programmes ended following the eradication of smallpox; the original (first generation) smallpox vaccines are no longer available to the general public. In addition, protection for those who were vaccinated may have waned over time.

Smallpox and monkeypox vaccines, where available, are being deployed in a limited number of countries to manage close contacts. While smallpox vaccines have been shown to be protective against monkeypox, there is also one vaccine approved for prevention of monkeypox. This vaccine is based on a strain of vaccinia virus (known generically as modified vaccinia Ankara Bavarian Nordic strain, or MVA-BN). This vaccine has been approved for prevention of monkeypox in Canada and the United States of America. In the European Union, this vaccine has been approved for prevention of smallpox. An antiviral to treat orthopoxviruses has been also recently approved in the United States of America and in the European Union. WHO has convened experts to review the latest data on smallpox and monkeypox vaccines, and to provide guidance on how and in what circumstances they should be used.

WHO advice

The advice provided hereafter by the WHO on actions required to respond to the multi-country monkeypox outbreak, is based on its technical work, and informed by consultations with the following existing WHO advisory bodies: the Strategic and Technical Advisory Group on Infectious Hazards (STAG-IH); the ad-hoc Strategic Advisory Group of Experts on Immunization (SAGE) working group on smallpox and monkeypox vaccines; the Emergencies Social Science Technical Working Group; the Advisory Committee on Variola Virus Research; WHO Research & Development (R&D) Blueprint consultation: monkeypox research; the Scientific Advisory Group for the Origins of Novel Pathogens (SAGO); as well as by the outcome of ad-hoc experts meetings.

All countries should be on the alert for signals related to people presenting with a rash that progresses in sequential stages — macules, papules, vesicles, pustules, scabs, at the same stage of development over all affected areas of the body — that may be associated with fever, enlarged lymph nodes, back pain, and muscle aches. During this current outbreak, many individuals are presenting with localized rash — peri-genital and/or peri-anal distribution associated with local, painful swollen lymph nodes. Some cases may have secondary bacterial infections and may have simultaneous sexually transmitted infections such as herpes simplex virus, syphilis or N. gonorrhoea. These individuals may present to various community and health care settings including but not limited to primary and secondary care, fever clinics, sexual health services, infectious disease units, obstetrics and gynaecology, emergency departments and dermatology clinics.

Increasing awareness among potentially affected communities, as well as health care providers and laboratory workers, is essential for identifying and preventing further cases and effective management of the current outbreak. Information should reach those who need it most during upcoming potentially amplifying large gatherings, and all efforts should be made to avoid unnecessary stigmatization of individuals and communities potentially affected by monkeypox.

Any individual meeting the definition for a suspected case should be offered testing. The decision to test should be based on both clinical and epidemiological factors, linked to an assessment of the likelihood of infection. Due to the range of conditions that cause skin rashes and because clinical presentation may more often be atypical in this outbreak, it can be challenging to differentiate monkeypox solely based on the clinical presentation.

Caring for patients with suspected or confirmed monkeypox requires early recognition through screening protocols adapted to local settings; prompt isolation and rapid implementation of appropriate IPC measures (standard and transmission-based precautions); testing to confirm diagnosis; symptomatic management of patients with mild or uncomplicated monkeypox; and monitoring for and treatment of complications and life-threatening conditions such as progression of skin lesions, secondary infection of skin lesions, and rarely, severe dehydration, severe pneumonia or sepsis.

Infection prevention and control (IPC) measures (including supportive isolation of confirmed cases) should remain in place until lesions have crusted, scabs have fallen off and a fresh layer of skin has formed underneath.

WHO is closely monitoring the situation and supporting international coordination working with Member States and partners.

For WHO documents available publicly, see the Public Health Response section above. Key highlights from these documents and those under development are provided below for ease of reference.

***Surveillance and reporting ***

A global minimum data set has been created by WHO to facilitate capturing the key epidemiologic parameters on cases, for the purposes of global situational awareness and reporting. Member States are requested to submit the minimum data on all cases meeting the case definitions of probable or confirmed cases, through their IHR National Focal Points to their respective WHO Regional IHR Focal Points, as soon as the data are available. The data will be aggregated and shared publicly in aggregate form on a regular basis through WHO information products. A separate Case Investigation and Contact Tracing form for Member States’ own use is currently being finalized and will be shared as soon as available.

Laboratory testing and sample management

There is an increasing number of commercial PCR kits available on the market, some specific for monkeypox virus detection, some for orthopoxvirus detection. Almost all of them are for research use only, and none is independently validated. Various sets of primers and probes to set up in-house PCR protocols are mentioned in the scientific literature.

Risk communication and community engagement

Communicating monkeypox-related risks and engaging at-risk and affected communities, community leaders, civil society organizations, and health care providers, including those at sexual health clinics, on prevention, detection and care, is essential for preventing further secondary cases and effectively managing the current outbreak. Providing public health advice on how the disease transmits, its symptoms and preventive measures and targeting community engagement to the population groups who are most at-risk is critical to minimize spread.

Anyone who has direct contact, including but not limited to sexual contact, with an infected person can get monkeypox. Steps for self-protection include avoiding sexual contact with someone with a localized anogenital rash and limiting the number of sex partners; avoiding close contact with someone who has symptoms consistent with possible monkeypox infection; keeping hands clean with water and soap or alcohol-based gels; and maintaining respiratory etiquette.

If a person develops symptoms such as a rash with blisters on face, hands, feet, eyes, mouth, and/or genitals and peri-anal areas; fever; swollen lymph nodes; headaches; muscle aches; and fatigue they should contact their health care provider and get tested for monkeypox. If someone is suspected or confirmed as having monkeypox, they should isolate, avoid skin-to-skin and face-to-face contact with others and abstain from sex, including oral sex, until the scabs have fallen off. During this period, cases can get supportive treatment to ease symptoms. Anyone caring for a person sick with monkeypox should use appropriate personal protective measures as mentioned above.

Residents and travellers to monkeypox-endemic countries should avoid contact with sick mammals such as rodents, marsupials, non-human primates (dead or alive) that could harbour monkeypox virus and should refrain from eating or handling wild game (bush meat).

It is also important to prevent the spread of rumours and misinformation around monkeypox. It is important for public health authorities to systematically listen to and analyse public health concerns, including through social media, identify key questions and information voids, and build resilience to misinformation. Members of the public should be encouraged to get information only from verified and credible sources.

Infection, prevention and control in health care settings

Implementation of appropriate IPC measures is essential to mitigate and control the transmission of monkeypox in health care and community settings; this includes the application of a hierarchy of controls (administrative, environmental and engineering controls) and the use of PPE to reduce the risk of exposure to monkeypox within health care settings. Health workers should apply standard precautions regularly, this includes conducting a risk assessment for every patient interaction, respiratory hygiene and cough etiquette, patient placement, PPE, aseptic technique, safe injections and sharps injury prevention, environmental cleaning and disinfection, proper handling of laundry and linen, decontamination and reprocessing of reusable patient care items and equipment, and waste management. WHO advises that IPC measures should be implemented for any suspected or confirmed case of monkeypox.

Clinical management and treatment

The majority of human monkeypox cases experience mild to moderate symptoms. Patients with monkeypox should be given symptomatic treatment for mild symptoms such as antipyretics for fever and analgesics for pain. Skin lesions should be kept clean. Adequate nutrition and rehydration are important. Patients should be counselled about signs and symptoms of complications which require urgent care.

Though uncommon, patients with monkeypox may develop severe and life-threatening complications. For example, the skin lesions are susceptible to bacterial skin and soft tissue infections. The lesions may be extremely itchy and if secondary bacterial infection occur from scratching it may requiring meticulous local wound care and, in some cases, antimicrobial therapy. Lesions in the mouth or the eye mucosa may also be present. Complications in endemic countries include secondary skin bacterial infections, dehydration, conjuctivitis, keratitis, pneumonia, sepsis or septic shock, and in rare cases encephalitis and death. It therefore follows that clinical care should focus on the management of clinical syndrome, maintenance of nutritional and hydration status, and prevention of complications and sequelae, as and when needed.

In patients with monkeypox, antivirals should be used under randomized clinical trials with collection of standardized clinical and patient outcome data to rapidly increase evidence generation on efficacy and safety. If this is not possible, antivirals may be used under expanded access protocols, such as Monitored Emergency Use of Unregistered and Investigational Interventions (MEURI).

Vaccines and immunization

There is a vaccine for monkeypox recently approved by some countries for which supplies are limited. Some countries may hold smallpox vaccine products which could be considered for use according to national guidance. Vaccine products may be available in limited quantities through national authorities, depending on the country.

Regardless of vaccine supply, mass vaccination of the population is not required nor recommended for monkeypox; every effort must be made to control human-to-human spread of monkeypox through early case-finding and diagnosis, isolation and contact-tracing.

Post-exposure prophylaxis (PEP) is recommended for contacts of cases with an appropriate second- or third-generation smallpox or monkeypox vaccine, ideally within four days (and up to 14 days) of first exposure to prevent onset of disease.

Pre-exposure prophylaxis (PrEP) is recommended for health workers at high risk of exposure, laboratory personnel working with orthopoxviruses, clinical laboratory personnel performing diagnostic testing for monkeypox, and response team members as may be designated by public health authorities.

All decisions around immunization with smallpox or monkeypox vaccines should be based on an assessment of risks and benefits on a case-by-case basis, using shared clinical decision-making.

Implementation of vaccination should be accompanied by robust pharmacovigilance, and the conduct of vaccine effectiveness studies under clinical trial protocols is strongly encouraged.

One Health

Various wild mammals have been identified as susceptible to monkeypox virus in endemic areas. This includes rope squirrels, tree squirrels, Gambian pouched rats, dormice, non-human primates, among others. Some species are asymptomatic, especially species suspected of being reservoirs (rodents). Other species, such as monkeys and great apes, show skin rashes similar to those experienced by humans. Thus far, there are no reports of domestic animals being affected by the monkeypox virus. There are also no reports of human-to-animal transmission of monkeypox. However, there remains a hypothetical risk of human-to-animal transmission. Persons with monkeypox should ensure appropriate management of all waste (such as bandages) and potentially contaminated materials to prevent the disease from being transmitted from infected humans to susceptible animals at home (including pets), or to peri-domestic animals, especially rodents.

Large gatherings

Large gatherings may represent a conducive environment for the transmission of monkeypox virus if they entail close, prolonged and frequent interactions among people, which in turn could expose them to contact with lesions, body fluids, respiratory droplets and contaminated materials.

While postponing or cancelling gatherings in areas where monkeypox cases have been detected is not required as a default measure, precautionary measures can be considered as follows:

Information on epidemiology, transmission and prevention of monkeypox should be shared with prospective attendees of large gatherings; such events should be used as opportunities for information outreach and community engagement;

Although monkeypox and COVID-19 spread between people differently, some of the COVID-19 measures applied during social gatherings such as keeping a physical distance and practicing regular handwashing are also effective against the transmission of monkeypox virus.

Close contact with someone who has signs and symptoms consistent with monkeypox should be avoided, including sexual contact.

Attendance lists for participants in gatherings can be introduced, if applicable, to facilitate contact tracing in the event that a monkeypox case is identified.

Staff responsible for dealing with attendees who fall ill at the event should be provided with information on how to manage people with signs and symptoms consistent with monkeypox.

As it is standard practice for large gatherings, and even more so during the COVID-19 pandemic, authorities and event organizers are invited to apply the WHO recommended risk-based approach to decision-making for mass gatherings, and tailor it to the large or small social events under consideration. In the context of the current outbreak, monkeypox-associated risks should be considered and factored in.

International travel

Based on available information at this time, WHO does not recommend that States Parties adopt any international travel-related measure for either incoming or outgoing travellers.

Any rash-like illness during travel or upon return should be immediately reported to a health professional, including information about all recent travel, sexual history and smallpox immunization history. Individuals who have been identified as contacts of monkeypox cases and, therefore, are subject to health monitoring, should avoid undertaking any travel, including international, until completion of their health monitoring period.

WHO urges all Member States, health authorities at all levels, clinicians, health and social sector partners, and academic, research and commercial partners to respond quickly to contain local spread and, by extension, the multi-country outbreak of monkeypox. Rapid action must be taken before the virus can be allowed to further establish itself as a human pathogen with efficient person-to-person transmission in both endemic and non-endemic contexts.

Dozens Feared Dead in Nigeria Church Attack

Dozens of worshippers were feared dead in an attack on a Catholic church in Nigeria on Sunday, state lawmakers said.

Legislator Ogunmolasuyi Oluwole said the attackers targeted the St. Francis Catholic Church in Ondo state just as the worshippers gathered on Pentecost Sunday, with gunmen opening fire and detonating explosives. He said that numerous children were among the dead.

The Vatican said that Pope Francis “prays for the victims and for the country, painfully attacked at a time of celebration, and he entrusts everyone to the Lord, that God might send His Spirit to console them.”

“It is a black Sunday in Owo. Our hearts are heavy,” Ondo Governor Rotimi Akeredolu tweeted Sunday. “Our peace and tranquility have been attacked by the enemies of the people.”

The governor was away in Abuja, taking part in his party’s primary elections ahead of next year’s polls but suspended his activities and returned to Ondo hours later with state security officials.

Akeredolu said that the attackers would be hunted and prosecuted. He also urged residents to remain calm and not resort to retaliation. There has been no claim of responsibility for the attack.

There was no immediate death toll, but Adelegbe Timileyin, who represents Nigeria’s lower legislative chamber, said at least 50 people had been killed, while others said the figure would turn out to be higher. Video footage of the scene showed worshippers lying in pools of blood as people around them wailed.

It was not immediately clear who was behind the attack. While much of Nigeria has struggled with security issues, Ondo is widely known as one of Nigeria’s most peaceful states. The state, though, has been caught up in a rising violent conflict between farmers and herders.

“In the history of Owo, we have never experienced such an ugly incident,” said lawmaker Oluwole. “This is too much.”

The Christian Association of Nigeria condemned the attack, with spokesman Bayo Oladeji saying, “What happened in Owo today is an unprovoked attack on innocent people worshipping God and to [the] Christian Association of Nigeria, it is condemnable; it is unacceptable. We’re tired of people going to church and being killed.”

Church officials said many of the wounded were fighting for their lives in hospitals. Some residents launched a blood donation drive to help them.

Nigeria is currently facing a wave of violence by armed gangs. A week ago, the prelate of the Methodist Church of Nigeria, Samuel Kanu Uche, was kidnapped on his way to the airport in southeastern Abia state.

He was released two days later after the church raised about $240,000 and paid the kidnappers.

Huge Europe-Morocco Migration Begins after COVID Hiatus

Morocco on Sunday begins welcoming an influx of its citizens living in Europe after the pandemic led to a halt in what has been called one of the world’s biggest cross-continental migrations.

The last such effort in the summer of 2019 saw 3.3 million people and more than three quarters of a million vehicles cross the Gibraltar Strait.

The North African kingdom is just 14 kilometers from the coast of Spain, which has announced it will also put in place special measures for Moroccans from June 15 for two months.

Spain’s government has called the seasonal migration “one of the biggest flows of people across continents in such a small time.”

Resuming large-scale cross-strait travel comes not only after an easing of the pandemic threat but also following a mending of diplomatic ties between the two countries.

The year-long diplomatic dispute had extended border closures originally put in place because of Covid-19, but maritime traffic resumed in April.

“Operation Marhaba [Welcome] for Moroccans living overseas begins on June 5,” said a statement late Saturday from the Mohammed V Solidarity Foundation which organizes the effort.

More than 1,000 people including doctors, social workers and volunteers have signed up to help people arriving at ports and airports.

Most will come by boat from Spain.

As well as at Moroccan ports, helpers will be stationed in the Spanish ports of Almeria and Algeciras, Marseille in France and Italy’s Genoa, among others.

The traffic goes in both directions, as many Moroccans also head to Spanish coastal resorts for their holidays.
