TEHRAN, March 10 (Xinhua) -- Iran's Foreign Ministry on Saturday strongly condemned a Friday raid on the Iranian embassy in London.

Foreign Ministry Spokesman Bahram Qasemi said in a statement that Iran has expressed its "strong protest to the British ambassador in Tehran and demanded that the British police fully protect our diplomats in London."

Iran also demanded punishment of the people behind the raid, said Qasemi.

On Friday, a group of four men raided the Iranian embassy in London and pulled down Iran's flag.

Local reports said they were supporters of a radial religious cult.

No one was hurt during the incident and the assailants were arrested.
