Chief of Egyptian Ambulance reported on Sunday that one Coptic protester  died of birdshot wounds during protests outside Saint Mark's Coptic Orthodox Cathedral in Cairo. The shots took place as thousands were mourning four men who were killed in Egypt's most recent sectarian violence. Four Christians and one Muslim man were killed in the northern town of Khusus over the weekend when the two groups exchanged fire, security sources had reported. Carrying wooden crosses and chanting religious slogans, the mourners demanded justice and the fall of the Muslim Brotherhood regime,  reported the state news agency. Confrontations erupted in Ramsis Street outside the cathedral with mourners and assailants clashing and some mourners cutting off the road.
