The head of Islamic State in Afghanistan, Abu Saad Erhabi, was killed in a strike on the group's hideouts in Nangarhar province on Saturday night, authorities said on Sunday. Ten other members of the militant group were also killed in a joint ground and air operation by Afghan and foreign forces, the National Directorate of Security in Kabul said in a statement. Lieutenant-Colonel Martin O'Donnell, a spokesman for US forces in Afghanistan, said the United States carried out a strike in Afghanistan on Saturday against a 'senior leader of a designated terrorist organization.' The provincial governor of Nangarhar said Erhabi was the fourth Islamic State leader in Afghanistan to be killed since July 2017.
