ISIS has released another video depicting the slaughter of Christians in Libya, showing footage of two massacres in which 30 Ethiopian Christians were killed. Before the executions a masked militant said: “To the nation of the cross, we’re back again... Muslim blood that was shed under the hands of your religion is not cheap.” “We swear to Allah ... you will not have safety even in your dreams until you embrace Islam,” he added. Later a militant with a Yemeni accent said: “Those who convert to Islam are safe. Those who refuse, we don’t have anything for them but the sword.” The atrocities were shown in a 29-minute video entitled Until There Came to Them Clear Evidence. In one massacre 15 Christians were beheaded; in the other 15 people were shot in the head. The video sought to justify the way Christians were treated in ISIS-held areas. Interviews were shown with a Christian mechanic and a doctor living in Raqqa who said they had paid the jizya, an extortion tax on non-Muslims, and were living under ISIS's protection. The video said Christians needed to either pay the jizya, convert to Islam or face being killed. In February a similar video was released showing the slaughter of 21 Christians from Egypt. Over the weekend Justin Welby, the Archbishop of Canterbury, was in Egypt to express his condolences over the killings. During his visit he met President al-Sisi, Pope Tawadros II, the head of the Egyptian Coptic Church, and Ahmed el-Tayeb, the grand imam of al-Azhar. He delivered letters of condolences.
