JALALABAD, Afghanistan, June 12 (Xinhua) -- Some four militants of the Islamic State (IS) were killed in a U.S. drone strike in Afghanistan's eastern province of Nangarhar Saturday night, the provincial government said on Sunday.
"An international forces' pilotless plane fired two missiles in Mahmando locality, Achin district last night. As a result four IS militants were killed," it said in a statement.
The Afghan security forces have beefed up security operations against militants recently as spring and summer known as fighting seasons are drawing near in the country.
Achin district bordering Pakistan has been the scene of heavy clashes between IS militants and security forces backed by pro-government local militiamen over the past couple of months.
The militant group has yet to make comments.
