A wave of anger that saw British, German and American embassies in Khartoum attacked by rioters swept across the Muslim world on Friday, with violent scenes playing out on streets from north Africa to south-east Asia.

The worst violence of the day was in the Sudanese capital, where protesters targeted the German embassy first, storming through the outer wall and setting fire to buildings and a car near the gates before they were pushed back by police firing teargas. German diplomats fled to the British embassy next door, which became the next target of the mob.

William Hague, the foreign secretary, said: “Sudanese police attended the scene, but demonstrators were able to break down a perimeter wall and cause minor damage to the compound. They did not attempt to gain access to the British embassy building.” No staff had been harmed, he added. Reports said at least one of the rioters had been killed in clashes with police.
