OMAN: Negotiations between Iran and the US over Tehran’s rapidly advancing nuclear programme will return tomorrow to the secluded sultanate, where experts on both sides will start hammering out the technical details of a possible deal.

The talks seek to limit Iran’s nuclear programme in exchange for the lifting of some of the crushing economic sanctions the US has imposed on the Islamic Republic.

US President Donald Trump has repeatedly threatened to unleash air strikes targeting Iran’s nuclear facilities if a deal isn’t reached.
