The United States does not have the will to reach an agreement to revive a 2015 nuclear deal with Iran at talks in Vienna where it is insisting on "unacceptable proposals", Iran's top security official, Ali Shamkhani, said on Thursday.
The 2015 deal that lifted sanctions on Iran in return for curbs on its nuclear program was on the verge of being restored after 11 months of negotiations until Russia presented a new obstacle by demanding written guarantees from the United States that Western sanctions over its invasion of Ukraine would not affect its trade with Iran.
