An important deadline for extending UN inspections is approaching May 21 in the Iran nuclear talks without any sign of a resolution in Vienna or an agreement to extend inspections.
Iran's Supreme Leader Ali khamenei has made defiant remarks about uranium enrichment but has not opposed a temporary inspection deal reached with the IAEA.
As the head of the IAEA is visiting Iran, Tehran says it is set to stop UN nuclear snap inspections and insists on US first lifting sanctions before rejoining JCPOA.
Iran's Supreme Leader Ali Khamenei has said that he expects "actions, not words" from the United States regarding the revivial of the 2015 nuclear agreement.
Iran has reiterated its intention to reduce UN nuclear inspection from February 21 if other participants in its 2015 nuclear deal did not respect their commitments.
