U.N. atomic watchdog chief Rafael Grossi appealed to Iran's leadership on Tuesday to take steps to resolve longstanding issues with his agency a day before he arrives in the Iranian capital for crunch talks over its nuclear programme, Paralel.Az reports citing Reuters.

"I am far from being able to tell the international community ... what is happening. I would be in a very difficult position. So it's like they (Iran) have to help us, to help them to a certain extent," Grossi told Reuters on the sidelines of the COP29 climate summit in Baku.
