The city of El Fasher in Sudan looks like a "massive crime scene". Paramilitary group Rapid Support Forces (RSF) seized control six weeks ago. Since then, many bodies have been piled in streets. These await burial in mass graves or burning in large pits, satellite images show. British MPs say at least 60,000 people have been killed in the city in just three weeks. Sarah Champion, chair of the Commons international development select committee, said, "Our low estimate is 60,000 people have been killed there in the last three weeks." About 150,000 residents are missing and thought to still be inside the city, but their fate is unknown. The city is sealed off from outsiders, including UN war crimes investigators and aid groups. Nathaniel Raymond from Yale Humanitarian Research Lab describes El Fasher as eerily empty with deserted markets and no animals left. He said, "It's beginning to look a lot like a slaughterhouse." The RSF had promised UN access but the city remains closed. Aid groups wait nearby but have no safe passage yet. A UN source said, "There needs to be a security assessment before we can plan on sending assistance. Right now, there is no guarantee of safe passage or protection of civilians, aid workers or humanitarian assets." Many who have escaped report extreme hunger and malnutrition. Experts call El Fasher famine-stricken. Human rights experts say this may be the worst war crime in Sudan's civil war so far. The conflict has killed up to 400,000 people and displaced nearly 13 million in over 32 months. Amnesty International also reports a past RSF attack on Zamzam displacement camp near El Fasher, with civilian targeting, hostage taking, and destruction. They have called for war crimes investigations into RSF's actions.
