Egypt retaliates with air strikes after ISIS marches 21 Coptic Christians along a lonely Libyan beach and beheads them en masse for their faith

The video, released last night, shows ISIS fighters dressed head to toe in black, marching the captives, all wearing orange jumpsuits, to a beach. The 21 men, murdered because of their Christian faith, can be seen being forced onto their knees before they are beheaded simultaneously by the militants standing behind them. This morning Egyptian warplanes struck Islamic State (IS) targets in Libya, following the mass murder of Coptic Christians.
