CAIRO, Egypt (AP) - Decisive action is needed to prevent sectarian tensions from escalating in Egypt, the country's top Islamic leader said Tuesday in the wake of a fatal riot fanned by Muslim protests over a DVD deemed offensive to their faith.

The comments by Grand Imam Mohammed Sayyed Tantawi come after four people were killed when a crowd of 5,000 Muslims rioted Friday in a Christian neighborhood in Egypt's second-largest city of Alexandria.

"We should take quick action to bridge the chasm as soon as we hear about a conflict erupting between Muslims and Christians," Tantawi, quoting a famous Arabic poem, said on the sidelines of the opening of a six-day gathering of Anglican clerics from around the world being held in the Egyptian capital, Cairo.
