The European Union on Friday (September 14th) urged leaders in Arab and Muslim countries to "call immediately for peace and restraint" amid violent protests over an anti-Islam film.

EU foreign policy chief Catherine Ashton issued the appeal after angry mobs attacked the embassies of EU members Britain and Germany in Khartoum. US diplomatic missions have also been attacked in several Arab countries.

"I condemn in the strongest terms the attacks against diplomatic missions in several countries," Ashton said.

"It is vitally important that leaders across the affected regions call immediately for peace and restraint," she said.

European Commission President Jose Manuel Barroso condemned on Friday the attacks on the British and German embassies in Khartoum as unacceptable and against "the rules of the civilised world".

"Nothing justifies these kinds of attacks," Barroso said, noting that at a meeting with Egyptian President Mohamed Morsi Thursday, he had equally condemned the attacks on Islam which have sparked widespread protests in the Muslim world.

Two protesters were killed in Sudan on Friday as thousands of people demonstrated against the film, attacking the embassies of Britain, Germany and the United States.
