U.S. and Iran edge closer to deal with nuclear issue back in play

The U.S. and Iran are moving closer to a potential breakthrough in efforts to end the war, with Tehran showing a willingness to discuss issues related to its nuclear program that were previously off the table, according to a diplomat with knowledge of the talks. Iran is studying proposals related to its atomic activities that were presented by chief mediator Qatar, according to the diplomat, who asked not to be identified discussing sensitive information. Any concession on that issue could lead to a significant step forward in negotiations, which have been stagnating since the collapse of an interim peace deal agreed in June.
