IS militants abduct and kill 30

Militants linked to Islamic State group abducted and killed about 30 civilians, including children in central Afghanistan, officials said on Wednesday, raising concerns about the group's expanding presence beyond its eastern stronghold.

The killings occurred late on Tuesday north of Firoz Koh, the capital of Ghor province, with the local government calling it a revenge attack after a local IS commander was killed.

IS, which controls territory across Syria and Iraq and is making steady inroads in Afghanistan, has so far not officially claimed responsibility for the attack.
