U.S. forces launched an airstrike last month in Somalia targeting the leader of the Islamic State group, Abdulqadir Mumin. However, according to U.S. officials, it is unknown whether Mumin was one of the three militants belonging to the group who were killed in the strike.

U.S. Africa Command released a statement May 31 about the strike, which did not result in any civilian deaths. AFRICOM did not include any information about the target, however, according to a report from NBC News, three unnamed U.S. officials have since said it was Mumin.
