Some 200 Palestinian Christians staged a candlelit march in Jerusalem Wednesday to mourn Egyptian Copts killed by the Islamic State group in Libya, calling for stronger international action against the jihadists. The demonstrators carried four cardboard coffins decorated with gold crosses, and held up banners showing pictures of the 21 Coptic Christians who were beheaded by IS militants in a graphic video released Sunday. "We call on the international community to respond to the killing of in**cents," one banner read, as an Orthodox priest read out a eulogy for the dead. "We want to express solidarity with Egyptians and Copts, and to show how sad Palestinian Christians and Muslim friends are" about the deaths, said Nashat Filmon, 39.
