Iran’s Foreign Minister, Mohammad Javad Zarif, has told the BBC that support from Europe to preserve the 2015 nuclear deal in the face of US pressure has been better than expected.

Mr Zarif was speaking to the BBC’s Lyse Doucet in New York after a week in which the EU announced it would set up a special financial mechanism to allow companies to get around the sanctions reinstated by President Donald Trump, who abandoned the nuclear deal earlier this year.
