A Pakistani demonstrator holds up a plac

A Pakistani demonstrator holds up a placard during a protest in Lahore on May 21, 2010, against the published caricatures of Prophet Mohammed on Facebook. Pakistani protesters shouted "Death to Facebook", "Death to America" and burnt US flags, venting growing anger over "sacrilegious" caricatures of the Prophet Mohammed on the Internet. A Facebook user organised an "Everyone Draw Mohammed Day" competition to promote "freedom of expression", inspired by an American woman cartoonist, but sparked a major backlash in the conservative Muslim country of 170 million. Islam strictly prohibits the depiction of any prophet as blasphemous and the row has sparked comparison with protests across the Muslim world over the publication of satirical cartoons of Mohammed in European newspapers in 2006.
