Iran has warned that it will take measures against Britain after its decision to close the Islamic republic’s embassy in London, a foreign ministry spokesman said on Wednesday.

“The British government’s asking Iranian diplomats in London to leave this country is a passive and hasty action,” the Iranian foreign ministry spokesman Ramin Mehmanparast said in statements emailed to a news agency on Wednesday.

“Obviously the government of the Islamic Republic of Iran will take reciprocal action in this regard and holds the British government responsible for protecting the diplomatic properties and belongings in London,” he added.

“What happened at the British embassy in Tehran was unpredictable. It occured due to the anger of some demonstrators over Britain’s policies regarding the Islamic republic,” Mehmanparast said.

He noted that none of the British diplomats were hurt and said the judiciary was “dealing” with the “violators”.

Iran “is committed to international obligations, and considers unacceptable any aggression towards diplomats and diplomatic properties,” Mehmanparast added.

Earlier, top lawmaker Aladdin Brujerdi lashed out at Britain for shutting the Iranian embassy in London and warned of “repercussions” and urged other European Union nations not to follow suit.

“Britain is responsible for all the repercussions of its action,” Brujerdi, chairman of the Iranian parliamentary national security and foreign policy commission, told a news channel.

Mehmanparast and Brujerdi were responding to British Foreign Secretary William Hague who earlier said London was shutting its embassy in Tehran and ordering the immediate closure of Iran’s embassy to Britain.

Iranian diplomats had until Friday to leave the country, Hague said.

The announcement was in response to Tuesday’s storming of Britain’s embassy in Tehran by Iranian protesters who Hague said were likely sent by the Islamic republic’s rulers.
