The British Council says it has suspended work in Iran because of what it calls intimidation by the authorities there.
The cultural arm of the British government says in a statement that it halted operations after "cases of intimidation of our local staff in Iran."
The council said all 16 of its local staff had been told to resign by the authorities in Teheran.
British Council chief executive Martin Davidson said Thursday that no British staff had been able to get visas to work in Iran for two years. He said that without staff the council office had to close.
