He said if the E3's "destructive" action at the UN Security Council was eventually completed, Iran would take countermeasures. The 2015 Iran nuclear deal has been under strain since the U.S. withdrawal, prompting Iran to gradually reduce compliance. The UN Security Council on Friday failed to adopt a resolution that would extend sanctions relief for Iran. The sanctions are expected to take effect later this month if no new actions were taken in the Security Council. Iran's Supreme National Security Council announced on Saturday that the country's cooperation with the IAEA would be "effectively" suspended after the UN Security Council voted against extending the lifting of international sanctions on Tehran.
