Protests against the depiction of the Muslim Prophet Muhammad continue, with demonstrators objecting to both an anti-Islam film made in the United States and caricatures published in a French satirical magazine.

Police clashed with protesters in the Pakistani capital, Islamabad, where a crowd of about 1,000 students tried to reach an area of the city that houses embassies and government offices.

Hundreds of people also marched in Afghanistan's capital, chanting anti-American slogans during a peaceful protest.

In Iran, students shouted “death to France” as well as the United States as they protested outside the French embassy in Tehran.

The French weekly Charlie Hebdo featured several images of Muhammad in its Wednesday issue, including several of him naked.

In response to the magazine's actions, the French government announced it is closing its embassies, consulates, cultural centers and schools in 20 countries Friday as a precautionary measure.

White House spokesman Jay Carney said Wednesday officials questioned the editors' decision to publish the deeply offensive cartoons, but added that they did not question the right of the magazine to publish them. He also reiterated that any offense was “not in any way justification for violence.”

The protests first erupted last week in response to the low-budget Internet video that insults Muhammad. During the protests, the American ambassador in Libya and three of his staff were killed in an attack on the U.S. consulate in Benghazi.
