Britain's Foreign Secretary William Hague says London is withdrawing its diplomatic staff from Iran and that the Iranian Embassy in London will be closed.
Addressing the UK parliament on Wednesday following the student protest outside the UK Embassy in Tehran, Hague said the Iranian Embassy in London will be immediately closed and its diplomatic mission will be expelled from Britain.
Hague added that British diplomatic staff in Tehran has been evacuated, the state-run BBC reported.
Hundreds of Iranian students staged a protest rally outside the UK Embassy in Tehran on Tuesday, pulling down the UK flag and demanding the expulsion of the British envoy.
Protesters also staged another gathering outside a second British diplomatic compound in northern Tehran.
Deputy Commander of the Iranian police Brigadier General Ahmad-Reza Radan told Britain's Ambassador to Tehran Dominick John Chilcott earlier on Wednesday that a number of the individuals who entered the embassy compound on Tuesday were arrested. He added that some of the other persons of interest have been identified and will be apprehended.
Iran's Foreign Ministry expressed regret in a statement on Tuesday over the “unacceptable actions” of a number of protesters during the demonstration in front of the embassy.
