Story highlights Afghan agency: Hafiz Saeed was killed with 30 other insurgents

Saeed is believed to have been an ISIS leader who had been with the Taliban

Spokesman: Man killed isn't the same one facing $10 million U.S. bounty

(CNN) A former Taliban leader thought to be ISIS' leader in Afghanistan and Pakistan has been killed in a U.S. drone strike, Afghanistan's intelligence agency said Saturday.

In a statement, the National Directorate of Security reported that Hafiz Saeed was killed along with 30 other insurgents in a strike on their compound in the Achin region of Nangarhar Province.

"As a result of efforts made by the NDS, the location of ISIS fighters' gathering was found and the information was shared with the coalition forces who then carried out an airstrike on them," the Afghan agency said.

U.S. Army Col. Brian Tribus said American forces conducted a strike in Achin on Friday against "individuals threatening the force." He did not elaborate.

The strike represents a seemingly big victory in Afghanistan's fight against ISIS, a terrorist group that has been blamed for numerous atrocities and conquered vast swaths of territory in Iraq and Syria while branching out with affiliates elsewhere.
