"The Afghan Special Operations Forces conducted an airstrike on Thursday, in Dih Bala district, Nangarhar province, against the IS terrorist group. As a result eight IS members were killed," Operational Coordination Group Afghanistan (MoD-OCGA) said in a statement.

In neighboring Kunar province, one IS fighter was killed in a similar attack in Chawkay district on the same day, according to the statement.

The statement did not provide information about the identity of the killed, saying more details about the targeted militants will be made public soon.
