IS leader in Afghanistan killed, US believes
Last year, the Afghan intelligence agency said it believed Saeed Khan had died in a drone attack in Afghanistan's eastern province of Nangarhar.
However, IS insisted its leader had survived that attack.
On Friday, the US said he had been killed in a new drone attack in Nangarhar's Achin district on 26 July.
The drone strike was carried out three days after IS carried out its most devastating attack in Afghanistan, killing 80 people and wounding 230 at a rally of Shia Muslims from the Hazara minority in the capital Kabul.
IS, a Sunni Muslim group, regards Shia as heretics.
Military operation
Pentagon spokesman Gordon Trowbridge said Saeed Khan had been killed in an "air strike", without specifying if a drone had been used.
"Khan was known to directly participate in attacks against US and coalition forces, and the actions of his network terrorized Afghans, especially in Nangarhar," Mr Trowbridge added.
