Negotiations to revive the Iran nuclear deal have entered a “critical” stage during which some key issues still need to be resolved, Tehran’s top diplomat said on Wednesday.
The 2015 accord had offered Iran sanctions relief in return for curbs on its nuclear programme, but the US unilaterally withdrew in 2018 under then-president Donald Trump.
Western powers that have been locked in nuclear talks with Iran have said in the past week that a deal was within reach while stressing the ball was in the Islamic republic’s court.
