Libyans angry over caricatures of the Prophet Muhammad rioted at the Italian consulate on Friday, storming the building and setting it on fire. A diplomat said at least 10 people were killed in clashes with police. It was the deadliest demonstration yet against the cartoons, which have set off violent protests throughout the Muslim world. At least 29 people have been killed altogether. In Pakistan, a cleric announced a $1 million bounty for killing the cartoonist. Denmark, where a newspaper first published the cartoons, temporarily closed its embassy in Pakistan and advised its citizens to leave the country. The Associated Press quoted Libyan security officials as saying 11 people were killed or wounded during the riot in the eastern city of Benghazi when police firing bullets and tear gas tried to contain more than 1,000 demonstrators hurling rocks and bottles. The casualties included police officers, but the officials declined to say how many people had died. Rioters charged the consular compound and set fire to the first floor of the building, the Italian Foreign Ministry said. Domenico Bellantone, an Italian diplomat, said 10 or 11 people - all Libyan - had died.
