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 mass civilian killings following the RSF takeover of the city in the Darfur region on Sunday.

The UN Security Council is expected to hold a meeting on Sudan, which is in its third year of civil war between the army and the paramilitary fighters.

The RSF leader spoke after international outrage about reports of mass killings in el -Fasher, apparently documented by his paramilitary fighters in social media videos.

Hemedti said he was sorry for the disaster that had befallen the people of el-Fasher and admitted there had been violations by his forces, which would be investigated by a committee that has now arrived in the city.
