Cairo's Muslims and Christians clash in Imbaba

Up to 200 people have been killed or injured during clashes between Muslims and Christians in Cairo, Egyptian officials say.

The clashes - in the suburb of Imbaba - came after Muslims attacked a church to free a Christian woman, witnesses said.

They alleged she was being held against her will because she wanted to convert to Islam.

Soldiers and police, backed by tanks, fired guns and tear gas to separate the groups, according to reports.
