The Socio-Economic Rights and Accountability Project (SERAP) has urged United Nations Secretary-General António Guterres “to urgently invoke Article 99 of the UN Charter and bring Nigeria’s escalating insecurity—marked by mass abductions, killings, attacks on civilians, mass displacement, and other grave human rights violations—to the attention of the UN Security Council.”

SERAP said: “Nigeria’s escalating insecurity and grave human rights violations are reflected in repeated abductions, killings, attacks on civilians, and mass displacement in Oyo, Benue, Borno, Plateau, Kaduna, Zamfara, and several other parts of the country.”

In the open letter dated 30 May 2026 and signed by SERAP deputy director Kolawole Oluwadare, the organisation said: “The scale, persistence, and regional implications of the insecurity and grave human rights crisis in Nigeria pose a threat to international peace and security and risk aggravating existing threats in the region.”

SERAP further said: “Article 99 of the UN Charter is designed precisely for situations in which emerging or ongoing crises require urgent preventive diplomacy, sustained international scrutiny, and coordinated international action.”

According to SERAP, “Several years of violence and conflicts in several states have created appalling human suffering, physical destruction and collective trauma across Nigeria. Our appeal is grounded in the preventive mandate of the UN Charter and the urgent need to address a rapidly deteriorating situation in the country.”

The letter reads in part: “Article 99 of the UN Charter provides that: ‘The Secretary-General may bring to the attention of the Security Council any matter which in his opinion may threaten the maintenance of international peace and security.’

“Placing the escalating insecurity and grave human rights violations in Nigeria on the Security Council’s formal agenda would strengthen the credibility and effectiveness of the United Nations system in fulfilling its primary responsibility for the maintenance of international peace and security.

“It would also ensure sustained international attention to attacks on civilians, including abductions, killings, and displacement.

“The crisis in Nigeria is not merely a domestic law-enforcement issue. Its effects increasingly implicate regional peace and security through cross-border movement of armed groups and weapons, large-scale displacement, growing instability extending beyond Nigeria’s borders, and weakening human rights protection and rule-of-law institutions.

“There is no effective protection of people and communities, with frequent reports of a pattern of large-scale violence across multiple states.

“Nigeria is facing a grave and worsening security crisis marked by repeated mass abductions of schoolchildren, teachers, women, commuters, and rural residents; attacks on villages and farming communities; killings by armed groups and criminal networks; and widespread displacement.

“Communities in Oyo, Benue, Borno, and across Nigeria continue to suffer repeated attacks with devastating consequences for civilian life, dignity, and security. The recent abductions of pupils and teachers in Oyo State illustrate the severity of the crisis facing civilian populations.

“On or about 15 May 2026, armed men reportedly attacked multiple schools in Ahoro Esinele community in Oriire Local Government Area of Oyo State, including Community Grammar School, Baptist Nursery and Primary School, and L.A. Primary School.

“During the coordinated attacks, at least 25 pupils and seven teachers were abducted. An assistant headmaster was reportedly killed, while another teacher later died in captivity.

“Distressing videos later circulated showing one abducted teacher, the vice principal of Community Grammar School, pleading publicly with President Bola Tinubu, Governor Seyi Makinde, and Nigerians to secure the release of the victims. Abductees are being held in harsh conditions, exposed to extreme weather, and called for urgent dialogue to save their lives.

“This incident highlights the devastating human consequences of recurring abductions targeting schools, children, and education workers, and underscores the urgent need for strengthened civilian protection, accountability, and prevention measures.

“Available information also indicates that gunmen recently abducted secondary school students and other travellers in Benue State while they were travelling to sit university entrance examinations.

“There are also reports of escalating attacks by non-state armed groups in the North-East, North-West, and North-Central regions. Recent bomb explosions in Maiduguri, Borno State, reportedly killed at least 23 people and injured over 100 others.

“These attacks have been accompanied by repeated assaults on military formations, attacks on internally displaced persons’ camps, abductions of women and children, and killings of civilians in rural communities.

“In Katsina State, gunmen recently killed at least 10 people, including women and children. In separate incidents, coordinated raids left at least 20 people dead and resulted in abductions of residents. In Adamawa State, another attack reportedly killed at least 29 people.

“Taken together, these incidents reflect an intensifying security crisis characterised by mass killings, abductions, and sustained attacks on rural communities.

“The situation is rapidly deteriorating into a humanitarian and security crisis with potentially far-reaching consequences for Nigerians as a whole and for peace, security and stability across the West African subregion. This outcome must be urgently prevented.

“Recent statements by United Nations officials have underscored the growing international concern about the worsening insecurity and grave human rights violations in Nigeria. In June 2025, you condemned the killing of people in Benue State and called for those responsible to be found and apprehended.

“In February 2026, you also condemned the terrorist attack in Kwara State, reaffirmed the solidarity of the United Nations with Nigeria, and stressed the need to bring perpetrators to justice.

“In November 2025, the Office of the United Nations High Commissioner for Human Rights expressed shock at the surge in mass abductions in Nigeria and urged authorities at all levels to take all lawful measures to halt such attacks, ensure accountability, and secure the safe return of victims.

“The United Nations has also warned that insecurity in Nigeria is generating wider humanitarian and regional consequences. The UN Resident and Humanitarian Coordinator in Nigeria has noted that violence across multiple regions has displaced millions, disrupted livelihoods, and deepened one of the country’s most severe humanitarian crises in recent years.

“UN agencies have also raised concerns that persistent attacks and instability are worsening food insecurity and increasing pressure on communities within Nigeria and across the wider region.

“These repeated warnings confirm that the crisis is not merely a domestic concern, but one with serious human rights, humanitarian, and regional peace and security implications.

“The Secretary-General’s recent invocation of Article 99 in relation to Gaza reaffirmed the importance of this role in situations involving large-scale human suffering, humanitarian emergency, and risks of wider regional destabilisation.

“It demonstrated the importance of timely action where national crises have cross-border consequences, including displacement and insecurity.

“Under international human rights law, state responsibility extends beyond refraining from direct violations. Nigerian authorities may incur responsibility where they fail to exercise due diligence to prevent, investigate, punish, and remedy abuses by non-state actors where risks are known or reasonably foreseeable.

“The recurring pattern of abductions, attacks, enforced disappearances, killings, and violence across Nigeria demonstrates that these risks are well known, repeatedly documented, and foreseeable.

“Where such threats persist without adequate preventive protection, effective investigation, or accountability, serious concerns arise under international human rights law including the UN Charter.

“The continuing insecurity across Nigeria has resulted, and continues to result, in devastating loss of life, destruction of communities, and widespread fear affecting millions. The persistence of these attacks, their humanitarian consequences, and their implications for regional stability require urgent international attention.”

SERAP therefore urged Mr António Guterres to:

1. Exercise your authority under Article 99 and bring the situation in Nigeria to the attention of the Security Council without delay.

2. Encourage regular and public Security Council briefings on insecurity, abductions, and humanitarian consequences in Nigeria.

3. Request systematic reporting by relevant UN bodies on attacks, displacement, and humanitarian impacts.

4. Call on Nigerian authorities to take urgent measures to prevent attacks, protect civilians, and secure the release of abducted persons.

5. Urge prompt, independent, and effective investigations into all incidents and ensure accountability for perpetrators and enablers.

6. Publicly call on Nigerian authorities to uphold their human rights obligations and strengthen civilian protection measures.

7. Support measures to end impunity and ensure remedies and reparations for victims and affected communities.

8. Encourage the international community to use all available influence to prevent further escalation and protect people’s lives.
