Iran has detained eight local staff at the British embassy in Tehran on accusations of having a role in post-election riots, local reports said. The embassy has not yet confirmed the report from the semi-official Fars news agency, which did not name its source. Relations between the countries are strained after Tehran accused the UK of inflaming unrest, which London denies. Some 17 people are thought to have died in street protests after the disputed 12 June presidential poll. Tehran has expelled two British diplomats, and the UK has responded with a similar measure. "Eight local employees at the British embassy who had a considerable role in recent unrest were taken into custody," Fars said, without giving a source. The UK Foreign Office said in London: "We have in the last few days received a number of, sometimes confused, reports that British nationals or others with British connections have been detained. We continue to raise them with the Iranian authorities." Source: BBC
