Authorities say the head of Islamic State militants in Afghanistan has been killed in a strike on the group's hideouts in Nangarhar Province.

The National Security Directorate said that in addition to Abu Saad Erhabi, 10 other members of the militant group were also killed in a joint ground and air operation by Afghan and foreign forces on Aug. 25, 2018.


The Aug. 26, 2018 statement said a large amount of heavy and light weapons and ammunition were also destroyed.

There was no immediate confirmation of the report.

Amaq, the extremist group's news agency, carried no comment on the issue, and there was no reaction from the NATO-led Resolute Support mission.

Sometimes known as Islamic State Khorasan, the group has built a stronghold in Nangarhar, on Afghanistan's porous eastern border with Pakistan. It's now one of the country's most dangerous militant groups.

It's unclear exactly how many Islamic State fighters are in the country, because they frequently switch allegiances. The U.S. military estimates that there are about 2,000.
