Iranian embassy staff hurry away, under the glare of the media.
On Wednesday these diplomats were given 48 hours to leave the UK as relations between London and Tehran sink to a new low.
Britain's move comes after the storming of the British mission in Tehran earlier in the week, which London says could not have taken place without consent from Iranian authorities.
This hard-line Iranian cleric warned the U.N. and other European countries not to ally with Britain or they would incur the wrath of Iranians.
The U.N. has condemned the attack and some European countries have joined Britain in withdrawing their diplomats from Tehran.
The EU is considering banning oil imports from the world's fifth biggest exporter after the U.N. nuclear watchdog issued a report suggesting Iran is developing atom bomb technology.
