Iran has reportedly detained up to eight local employees of the British Embassy staff in Tehran.
Reports by the Iranian Fars news agency say the eight were detained on suspicion of involvement in recent political demonstrations in Iran.
The reports by the semi-official Fars news agency provided no further details.
The eight are accused of having played “a remarkable role” in the recent unrest.
The report comes as Fars also reported that Iranian Foreign Minister Seyed Sadeq Mahsouli said that U.S. funds had been used to finance recent unrest in Iran.
Iran’s rulers have accused the West of stoking unrest following the June 12 presidential election, singling out Britain and the US as prime instigators.
Last week, Iran expelled two British diplomats, prompting the expulsion of two Iranian diplomats from Britain.
