President Sisi had vowed to ‘avenge the criminal killings’ after release of video purporting to show killing of 21 Christians, believed to be kidnapped Egyptians Egypt reported that its war planes had struck Isis targets in Libya, shortly after President Abdel Fatah al-Sisi vowed revenge for the release by Isis-affiliated militants of a video of a mass killing of Christians. A spokesman for the Armed Forces General Command announced the strikes on state radio Monday, marking the first time Cairo had publicly acknowledged taking military action in neighbouring Libya. The statement said the warplanes targeted weapons caches and training camps before returning safely. It said the strikes were “to avenge the bloodshed and to seek retribution from the killers”. “Let those far and near know that Egyptians have a shield that protects them,” it said. Libya’s air force meanwhile announced it had launched strikes in the eastern city of Darna, which was taken over by an Isis affiliate last year. The announcement, on the Facebook page of the air force chief of staff, did not provide further details. The video, released on Sunday evening, claimed to show the mass beheading of 21 Christians – believed to be mostly Egyptians – kidnapped in Libya. The US said the video showed the “wanton killing of innocents” and the UK foreign minister condemned the “barbaric” act.
