Aid groups have estimated that over 100,000 people fled el-Fasher as a result of the siege, or over a third of the former population of 260,000. Experts at the Yale University Humanitarian Research Lab have said that satellite imagery shows the city was turned into a “slaughterhouse,” and British lawmakers said this month that they’ve been told that a “low estimate” of 60,000 people were killed over the course of just a few weeks during and following the takeover.

The atrocities have renewed calls in recent weeks from lawmakers to cut off the United Arab Emirates (UAE), which supplies the RSF with weapons, from the international arms trade.
