Christians, Muslims Clash in Egyptian Capital Can we peacefully coexist?

Egyptian security officials say at least 10 people have been injured in clashes between Muslim and Christian protesters in Cairo.

The clashes began late Saturday and lasted through early Sunday after a mob attacked a group of Coptic Christians staging a sit-in outside the state television building in central Cairo.

Witnesses say rocks were thrown and vehicles set on fire. Police and army troops fired shots in the air to disperse the crowd.

The violence came about a week after Muslim mobs attacked Egypt's Coptic Christian minority, burning two churches and leaving 12 people dead in Cairo's slum of Imbaba.

Christians make up about a tenth of Egypt's 80-million people. They joined forces with Muslims during the protests that ousted long-time president Hosni Mubarak earlier this year, but sectarian strife has since intensified.

An explosion was reported near the tomb of a prominent Muslim sheikh in the Sinai Peninsula on Saturday.
