A US drone strike killed on Tuesday a senior leader of ISIS in Afghanistan’s Nangarhar province, Afghan security officials said.
At least five other ISIS militants were killed in the same strike, officials added.
Shahidullah Shahid was believed to be the leader of the group’s “Khorasan region,” which ISIS uses to refer to a large area spanning Iran, Afghanistan and Pakistan.
Shahid’s death will hurt ISIS’ ability to recruit Afghan and Pakistani fighters, analysts say.
Shahid was a spokesman for the Pakistani Taliban before he pledged allegiance to ISIS in October 2014.
Afghanistan has witnessed rising levels of violence since NATO forces withdrew from the country in December 2014. The UN says 2014 was the most violent year yet since US forces invaded the country in 2001.
The US forces have been carrying out air raids against militants in Afghanistan to prevent them from gaining ground in the war-torn country.
In May, US strikes killed Abu Sayyaf in eastern Syria, a prominent ISIS figure who oversaw the petroleum and gas financing for the group.
