The leader of the Islamic State in Afghanistan, Abu Sayed was killed in a strike aimed at IS' headquarters along side other IS fighters, the Pengton said on Friday.
"The significance is you kill a leader of one of these groups and it sets them back ... it is obviously a victory on our side in terms of setting them back, it is the right direction," the US defence secretary, Jim Mattis was quoted by Reuters as saying.
Mr Sayeed was the third leader of IS in Afghanistan, his two predecessors, Abdul Hasib and Hafiz Saeed Khan having been killed in 2017 and 2016 respectively.
