An Egyptian security official says a Coptic Christian has died of burns sustained during sectarian clashes, raising the death toll to eight since the weekend.

The official says attackers doused Saber Helal, 26, with gasoline and set him on fire during clashes over the weekend between Muslims and Christians in Khosoos, a town north Cairo. Four other Christians and a Muslim were killed at the time.

The official said Helal died Thursday. He was speaking on condition of anonymity because he was not authorized to speak to the media.

More clashes broke out Sunday at Cairo's main Coptic Cathedral after funerals for the Christians killed in Khosoos. The church was attacked and two more people were killed, one of them a Christian, in the worst sectarian violence since last year.
