Sunday’s clashes grew out of Khossous, a town north of Cairo, where five people, including a Muslim, were killed a day earlier. Renewed clashes erupted there later Sunday outside the local church, leaving 12 residents and one police officer injured.
At the cathedral on Sunday, witness Ibrahim Elsherif said the clashes began when angry Coptic protesters tried to stop traffic for an anti-government march. A street brawl turned quickly into an attack by local residents, who pelted the protesters with rocks from the roofs of nearby buildings, throwing firebombs and firing birdshot, he said. Some protesters smashed parked cars.
One Coptic Christian was killed in the violence, and at least 66 people were wounded, the Health Ministry said. Two local journalists were among those injured, one seriously, according to their newspapers.
Video aired live on the private ONTV network showed young men on the roof of a building next to the cathedral firing handguns toward the compound.
Inside the cathedral, several thousand mourners chanted slogans against Morsi, calling on the Egyptian leader to step down. They shouted ‘‘Leave!’’ and ‘‘This is our country, we will not leave.’’
