Men in orange jumpsuits purported to be Egyptian Christians held captive by the Islamic State are marched by armed men along a beach said to be near Tripoli, in this still image from an undated video made available on social media on February 15, 2015. Islamic State released the video on Sunday purporting to show the beheading of 21 Egyptian Christians kidnapped in Libya. In the video, militants in black marched the captives to a beach that the group said was near Tripoli. They were forced down onto their knees, then beheaded. Egypt's state news agency MENA quoted the spokesman for the Coptic Church as confirming that 21 Egyptian Christians believed to be held by Islamic State were dead. | (Photo: Reuters/Social media via Reuters TV)
