The leader of Sudan's paramilitary Rapid Support Forces (RSF) has declared an investigation into what he called violations committed by his soldiers during the capture of el-Fasher. The announcement by Gen. Mohamed Hamdan Dagalo, known as Hemedti, came after escalating reports of civilian killings following the RSF takeover of the city in the Darfur region on Sunday. He spoke after international outrage about reports of mass killings in el-Fasher, apparently documented by his paramilitary fighters in social media videos. The RSF has since released footage that they say shows the arrest of a fighter accused of carrying out executions in el-Fasher. Footage previously verified by BBC Verify showed the man, who goes by the name Abu Lulu online, shooting unarmed people in an area outside el-Fasher. However, Tom Fletcher, the UN's top humanitarian official, emphasized the urgent need for accountability in light of the 'appalling news' from the region. As the crisis deepens, multiple international entities have called for investigations into the violence, reiterating the need to protect civilians in conflict zones.
