In South Sudan, at least 169 people were killed after dozens of armed assailants attacked a town near the border with Sudan. Victims included government soldiers and nearly 100 civilians, with women and children among the dead. A U.N. mission said it was sheltering more than 1,000 civilians who fled the violence. A local official said the attackers were fighters aligned with Riek Machar, one of two rivals for control of South Sudan during the five-year civil war that officially ended in 2018 after an estimated 400,000 people died from the fighting. Meanwhile, the medical charity Doctors Without Borders says 26 of its workers remain unaccounted for, a month after they fled attacks on two medical facilities in South Sudan’s Jonglei state.
