Volker Türk told the Human Rights Council that the investigation and analysis undertaken by his office, OHCHR, had revealed “an apparent total disregard for the protection of civilians during and after military operations.”

The OHCHR’s Fact-Finding Mission in the eastern DRC is also investigating other alleged violations of international humanitarian law, “many of which may amount to war crimes,” he said.

Arbitrary Arrests

After capturing cities and villages in early 2025, the M23 Rwanda-backed rebels arbitrarily arrested police officers and large numbers of other civilians, including children, the UN human rights office reported.

According to witnesses, those captured were, and are, still being held in “inhumane conditions,” and many were forcibly recruited into the ranks of the M23.

The Mission is also investigating alleged arbitrary arrests and enforced disappearances of suspected M23 supporters by the military intelligence arm of the DRC armed forces.

Extrajudicial Killings

OHCHR also reported that members of the M23 carried out summary and extrajudicial executions, which likely amount to war crimes, said Mr. Türk.

The Mission is also investigating alleged summary executions by members of the DRC armed forces and DRC-backed Wazalendo militias.

UN human rights is also investigating reports of death threats, detention and other reprisals against human rights defenders, journalists, and members of civil society perceived as critical of the M23; including the alleged killings of at least two activists.

Sexual Violence

The Mission received reports of “horrific” use of sexual violence by all parties as a means of reprisal against communities, relatives of perceived opponents, and people from other ethnic groups, said Mr. Türk.

In North and South Kivu, nearly 40 per cent of survivors of sexual and gender-based violence are children. The UN International Children’s Emergency Fund (UNICEF) estimated that during the most intense phase of the conflict, a child was raped every 30 minutes.

Mr. Türk called on “all parties to the conflict to commit immediately to a ceasefire and resume negotiations, and to respect international humanitarian and human rights law.”
