Deadly clashes over Coptic protest in Cairo

People were killed and scores more injured in clashes in the Egyptian capital, Cairo, after thousands took to the streets protesting against an attack on a Coptic Christian church.

The march started peacefully, until scuffles broke out between protesters and the military police.

Casualties were sustained on both sides, with dozens of people also getting arrested.

The violence is the worst since the 18-day uprising that ousted President Hosni Mubarak in February.
