On Sunday, the Rapid Support Forces (RSF), a paramilitary group, attacked civilians in a busy street market in Sennar city in south-eastern Sudan, killing at least 20 people and leaving 70 injured. Last month, another RSF attack in the same state killed at least 80. The war in Sudan has claimed at least 150,000 lives since it began last April, with both warring parties – Sudan’s military and the RSF – accused of war crimes and ethnic massacres against unarmed civilians. Yesterday, RSF atrocities were revealed with visual evidence for the first time in a Lighthouse Reports investigation published in association with other media outlets. The UN has called for the deployment of an international force and an arms embargo, but both proposals were rejected last week by Sudan’s military on the basis that they were “a flagrant violation of [the UN’s] mandate”. A separate ceasefire negotiation in Geneva last month also failed. And the scale of the disaster keeps growing.
