The Islamic republic has been crippled by a series of UN and US sanctions aimed at bringing an end to its nuclear drive, which the West claims is being used to develop atomic weapons. Iran denies the assertion.

Oil prices were also supported by strong US job and growth figures at the end of last week that exceeded forecasts and provided fresh evidence of a recovery in the world's biggest economy, Teoh said.
