A court in Pakistan has ordered the authorities to temporarily block the Facebook social networking site. The order came when a petition was filed after the site held a competition featuring caricatures of the Prophet Muhammad. <br/><br/>Justice Ejaz Ahmed Chaudhry of the Lahore High Court ordered the department of communications to block the website until 31 May, and to submit a written reply to the petition by that date.<br/><br/>The judge also directed Pakistan's foreign ministry to raise the issue at international level. The petition, filed by a lawyers' group called the Islamic Lawyers' Movement, said the contest was "blasphemous". <br/><br/>A message on the competition's information page said it was not trying to slander the average Muslim. Reports say publications of similar cartoons in Danish newspapers in 2005 sparked angry protests in Muslim countries and five people were killed in Pakistan.
