Iran's official IRNA news agency quoted Iran’s envoy to the International Atomic Energy Agency (IAEA), Kazem Gharibadadi, as saying that the visit this week is “neither related to the snapback mechanism nor the US demand.” He said the visit by the IAEA chief Rafael Grossi is Iran’s invitation.

Grossi’s visit comes as the US is putting pressure on Tehran to extend an arms embargo against Iran. However, 13 of 15 UN Security Council members have protested the US’s move.
