About 100 demonstrators threw stones and firebombs at the British Embassy in Teheran on Friday, damaging the building but harming nobody as they accused Britain and the United States of being accomplices in Israel's fight against Hizbullah.
Demonstrators also smashed some of the building's windows as they called for its closure and the expulsion of the British ambassador.
A British Foreign Office spokesman, on customary condition of anonymity, said nobody was harmed.
"Protesters were throwing bricks and at least one petrol bomb but everyone's OK," he said. "There was just some damage to perimeter of the embassy."
