Egyptian state TV says President Hosni Mubarak has ordered a night curfew from 6 p.m. to 7 a.m. in Cairo, the Mediterranean port city of Alexandria and the flashpoint city of Suez east of the capital. It said the military will work in tandem with the police to enforce the ban.
It was the most drastic measure so far to quell riots and protests that spiraled into chaos on Friday.
