(Reuters) The head of Islamic State in Afghanistan, Abu Sayed, was killed in a strike on the group’s headquarters in Kunar province earlier this week, the Pentagon said on Friday.

Pentagon spokeswoman Dana White said in a statement that other members of the Islamic State group were also killed in the strike on Tuesday.

U.S. Defense Secretary Jim Mattis told reporters, “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.”

Sayed is the third Islamic State leader in Afghanistan to be killed since July 2016.
