Britain's foreign secretary says the government is «deeply concerned» at the arrest and detention of British Embassy employees in Tehran. David Miliband, who is on the Greek island of Corfu for a foreign ministers' meeting, said Britain has protested to the Iranian authorities about the arrests, which he said occurred Saturday. The foreign secretary described the detentions as «harassment and intimidation of a kind that is quite unacceptable.» Iranian media reported Sunday that authorities had detained eight local employees of the British Embassy in Tehran for an alleged role in post election protests.
