Iran will not accept deadlines set by the West, FM spokesman says

Iran's Foreign Ministry spokesman said on Sunday that Tehran will not accept any deadline set by the West to revive the 2015 nuclear deal. 

He added that all "politically-motivated" claims by the UN watchdog IAEA about Tehran's nuclear work must be dropped.

The remarks came as Iran announced earlier on Sunday that its chief nuclear negotiator Ali Bagheri Kani will return to Vienna for talks on resolving the deal's remaining issues.
