Video shows killing of Ethiopians

Execution of migrant Christians by Islamic State extremists widens scope of atrocities

Islamic State militants in Libya shot and beheaded groups of captive Ethiopian Christians, a video purportedly from the extremists showed on Sunday. The attack widens the circle of nations affected by the group's atrocities while showing its growth beyond a self-declared caliphate in Syria and Iraq.

The release of the 29-minute video comes a day after Afghanistan's president blamed the extremists for a suicide attack in his country that killed at least 35 people - and underscores the chaos gripping Libya after its 2011 civil war and the killing of dictator Moammar Gadhafi.
