In Sudan, nearly two dozen people were killed Saturday in military airstrikes on a residential area of Omdurman, Sudan’s most populous city. It was one of the deadliest attacks in an urban area since fighting erupted in April between the Sudanese army and the Rapid Support Forces. At least 17 other people, including five children, were killed in an army air raid in Khartoum last month. The U.N. has warned Sudan is on the brink of a “full-scale civil war” as Egypt is hosting talks in Cairo this week on how to end the violence.
