Al-Fateh Abdullah Idris, better known by his nom-de-guerre Abu Lulu, and referred to as the Butcher of El Fasher, is a Sudanese military officer in the Rapid Support Forces (RSF) and convicted war criminal who became infamous for posting videos of himself executing civilians during the El Fasher massacre, and other massacres during the Sudanese civil war. He boasted of killing more than 2,000 people in El Fasher, and on 30 October 2025, he was arrested by the RSF. The RSF have since publicly distanced themselves from him, stating Abu Lulu was a leader of an allied militia. However, his arrest has been described as a publicity stunt by the RSF to defuse international ire to the massacre in El Fasher and other RSF atrocities.
