The Afghan military says its air force has targeted Islamic State militants in the eastern province of Nangarhar, killing at least 40 insurgents.
A Defense Ministry spokesman said the air strike took place late on April 14 in Achin district. He said several IS fighters were also wounded.
District Governor Gahlib Mujahid said the air strike targeted a meeting of IS fighters that was under way in the Pikha Lataband area.
He said most of the dead were foreign fighters and that their bodies were collected by local villagers and handed over to IS, which has gained a foothold in Nangarhar.
Nangarhar has seen heavy fighting between IS and Taliban fighters.
Analysts say many IS militants are former Taliban members weary of the insurgency's failure to overthrow the Kabul government.
