Egypt's military rulers have vowed to halt religion-related violence, a day after sectarian clashes in a Cairo suburb killed 12 people and wounded more than 200 others.
Military leaders said Sunday that 190 people detained in connection with the violence will face trial in a military court.
Egyptian Prime Minister Essam Sharaf canceled a tour of neighboring Gulf states and called an emergency Cabinet meeting in response to Saturday's clashes between Christians and Muslims.
Witnesses say Muslims converged on a Coptic church Saturday in the Cairo district of Imbaba in response to rumors that a Christian woman was being held there to prevent her from converting to Islam. Other reports said the crowd believed the woman had already converted and was being prevented from marrying a Muslim man.
Reports say members of the crowd began throwing firebombs and stones, setting some nearby buildings aflame. Security forces fired shots in the air and used tear gas to separate the two sides.
