Clashes broke out between Coptic Christians and Muslims in central Cairo after funeral of four Copts killed in sectarian violence outside capital, a witness says

Clashes broke out between Coptic Christians and Muslims in central Cairo today after the funeral of four Copts killed in sectarian violence outside the Egyptian capital on Friday night, a witness said.

The state news agency MENA said 17 people had been injured in fighting after a funeral ceremony at the city's Coptic Orthodox cathedral.

Public television showed riot police firing tear gas to disperse the crowd.

In some of the worst sectarian violence for months on Friday, four Christians and one Muslim were killed in El Khusus, north of Cairo, when members of both communities started shooting at each other.

New clashes erupted today when hundreds of angry Copts who had attended a funeral service at St. Mark's Cathedral spilled out into the streets of Cairo, chanting 'With our blood and soul we will sacrifice ourselves for the cross'.

After an emotional church service, where relatives of the dead wept, young Christians started hurling rocks at police officers, a witness said.
