Egyptian Police Block Roads To U.S. Embassy

Anti-American protests continue to percolate around the world, from Egypt to Australia, as hordes of protesters denounce a film by a California man lampooning the Prophet Muhammad.

Al-Qaeda's branch in Yemen praised the killing of the U.S. ambassador in Libya in an internet statement Saturday and called for more attacks to expel American embassies from Muslim nations.

Ambassador Chris Stevens and three other Americans were killed after an attack on the U.S. consulate in the Libyan city of Benghazi on Tuesday.

Al-Qaeda in the Arabian Peninsula called for protests to continue in Muslim nations "to set the fires blazing at these embassies," and said the killing of Stevens was "the best example" to follow.

In Cairo, police have blocked roads leading to the U.S. Embassy after four days of demonstrations in Egypt, and several other countries aimed at a 14-minute film that denigrates Islam and was made in California.

After another night of skirmishes with protesters, riot police rounded up hundreds of people early Saturday in the streets near the embassy and Tahrir Square.

CBC's Sasa Petricic, reporting from the edge of the square, said traffic is flowing and people are cleaning up after a violent night. He said police were moving huge concrete blocks into place to block the main street leading to the embassy.

"You can still smell the tear gas. There are burned-out cars, lots and lots of broken windows along pretty much all of the streets here, at banks, hotels and other buildings. It's really quite a mess."

Muslims angry over the film mocking the Prophet Muhammad took to the streets on Friday in more than 20 countries from the Mideast to Southeast Asia.

In most countries, protests were peaceful, if vehement. But deadly clashes erupted in several places. Protesters in Sudan and Tunisia tried to storm Western embassies, an American fast-food restaurant was set ablaze in Lebanon, and international peacekeepers were attacked in the Sinai.

The deployment of an elite team of U.S. Marines to Khartoum has also been delayed due to objections by Sudan's government. The Marine unit, known as a fleet anti-terrorism security team, was ordered to Sudan in the wake of violence and protests against the U.S. Embassy there.

The anti-U.S. protests that have spread to so many Muslim-dominated countries began in Cairo on Tuesday. One man died of birdshot in Cairo overnight near the U.S. Embassy.

Anger over the controversial film, entitled The Innocence of Muslims, is blamed for an assault late Tuesday on the U.S. consulate in Benghazi, Libya, where assailants launched a two-pronged attack that killed four Americans, including Ambassador Chris Stevens.

The only report Saturday of violence linked to the film came from Sydney, Australia, where riot police clashed with about 200 protesters at the U.S. consulate.

Ten Network television news showed a policeman knocked unconscious as the mostly male crowd hurled bottles and other projectiles. Police used pepper spray against the protesters, who chanted "Obama, Obama, we love Osama" and waved placards saying "Behead all those who insult the Prophet."

Six police were injured and two protesters were treated for police dog bites police said in a statement.
