The youngest son of al-Qaida chief Osama Bin Laden has called for Britain and its allies to be wiped out. Hamza Bin Laden (photo), 16, the youngest of the Saudi-born warlord?s 18 sons, is claimed to be the author of a poem featured on an extremist website to mark the third anniversary of the July 7 London bombings in which 52 innocent people died.

In the website, the boy dubbed the «Crown Prince of Terror», called for acceleration in the «destruction» of US, Britain, France and Denmark, the latter singled out for the publishing by its largest selling broadsheet of caricatures of the Prophet Mohammed. Patrick Mercer, the Conservative MP and a former shadow minister for security, said of the reading: ?We now have the Crown Prince of Terror taking up his father?s mantle.?
