Afghan forces mistakenly killed nine people, most of them civilians, during raid on a house in eastern Nangarhar province which has been a base for the Islamic State group and other militants, officials said on Tuesday. The raid, which took place late last night in Chaparhar district, also wounded eight other civilians, said provincial governor Hayatullah Hayat. A local police commander was among the dead, he added. According to the governor, gunfire had been coming from the house that was raided but the casualties were identified as mostly civilians once the operation ended. An investigation was underway to determine how the operation resulted in civilian casualties. Inamullah Miakhail, a spokesman for the hospital in Nangarhar, also confirmed that nine dead bodies were brought to the hospital from the raid.
