A group calling itself the “Islamic State in Palestine” spread fliers in east Jerusalem threatening that it would massacre all Christians who fail to evacuate the Holy City. The leaflets, which appeared on June 27, say that the Islamic State knows where the city’s Christians live, and warns that they have until Eid al-Fitr—July 19, when Ramadan ends—to leave the city or be slaughtered. The leaflet was emblazoned with the black flag associated with the Islamic State.
