Michelle Bachman, Republican candidate for the U.S. 2012 presidential elections told supporters that, following the attack on the British Embassy in Tehran on Tuesday, she would also close the U.S. embassy in Iran.

Having expressed her support for the British move to remove all its diplomatic staff from Iran, and to expel the Iranian diplomatic corps from the U.K., Bachmann said, “That’s exactly what I would do [if I were president]. We wouldn’t have an embassy in Iran. I wouldn’t allow that to be there,” ABC News reported.

The U.S., however, has not had a diplomatic mission in Iran since 1980. The U.S. cut all diplomatic ties with Iran after the hostage crisis, in which 52 Americans were held hostage for 444 days.

According to an ABC News report, Bachmann was addressing supporters in Waverly, Iowa, when she made the gaffe.

Only a few weeks ago, Bachman boasted, “I haven’t had a gaffe or something that I’ve done that has caused me to fall in the polls,” ABC News reported her as saying. 

Britain shut Iran's embassy in London and expelled its entire staff on Wednesday, saying the storming of the British mission in Tehran on Tuesday could not have taken place without consent from Iranian authorities.

"Our bigger, long-term concern is the Iranian nuclear program, the danger that poses to the peace of the Middle East and the wider world ... and it is for that reason that we will agree, I hope, today to intensify European Union sanctions on Iran," Hague said.

EU foreign ministers were meeting in Brussels to map out Europe's response to a report by the International Atomic Energy Agency in recent weeks that suggested Iran has worked on designing an atom bomb.

Meanwhile, German Foreign Minister Guido Westerwelle has recalled the country's ambassador to Iran, the Foreign Ministry in Berlin announced Wednesday

France recalled its ambassador to Tehran for "consultations" on Wednesday as well. Foreign Ministry spokesman Bernard Valero said in a statement that the ambassador, Bruno Foucher, had been recalled over Iran's "flagrant and unacceptable" violation of the Vienna Convention.

Italy's foreign minister said Wednesday that his country is considering closing its embassy in Tehran.
