Here's an Associated Press (AP) special report, datelined GENEVA.
Four years after cartoons of the prophet Muhammad set off violent protests across the Muslim world, Islamic nations are mounting a campaign for an international treaty to protect religious symbols and beliefs from mockery - essentially a ban on blasphemy that would put them on a collision course with free speech laws in the West.
Documents obtained by The Associated Press show that Algeria and Pakistan have taken the lead in lobbying to eventually bring the proposal to a vote in the U.N. General Assembly.
If ratified in countries that enshrine freedom of expression as a fundamental right, such a treaty would require them to limit free speech if it risks seriously offending religious believers. The process, though, will take years and no showdown is imminent.
The proposal faces stiff resistance from Western countries, including the United States, which in the past has brushed aside other U.N. treaties, such as one on the protection of migrant workers.
