France's new foreign minister said on Tuesday there were only a few weeks to revive Iran's 2015 nuclear deal with world powers, although a senior U.S. official made clear Washington had set no such deadline.
Catherine Colonna told lawmakers the situation was no longer tenable. She accused Iran of using delaying tactics and, during talks in Doha two weeks ago, of going back on previously agreed positions while forging ahead with its uranium enrichment programme.
