About 150 hard-line Iranian students threw stones and paint at the British Embassy and clashed with anti-riot police Thursday, protesting what they called Britain's interference in internal affairs. The students chanted "Death to England" and "close down the British Embassy" during the protest. Anti-riot police used batons during the clashes to block the students from entering the embassy, which is located in downtown Teheran. Some of the students accused Britain of seeking to provoke ethnic tensions in Iran and undermining Iran's security. They also called on the government to expel the British ambassador to Teheran.
