Iran’s foreign minister on Thursday dismissed as “foolish claims” US threats to trigger a return of all United Nations sanctions if the UN Security Council does not extend an arms embargo on Tehran, state media reported.

The US special envoy for Iran, Brian Hook, on Wednesday publicly confirmed the strategy two weeks after an official, speaking on condition of anonymity, said that Washington had notified Britain, France and Germany of its plan.

The UN embargo is due to expire in October under a 2015 Iran nuclear deal that US President Donald Trump quit in 2018.

Washington argues it can trigger a return of UN sanctions because a 2015 Security Council resolution enshrining the deal still names the United States as a participant.

“Foolish claims by US officials is nothing new,” Foreign Minister Mohammad Javad Zarif told reporters.

“It is no surprise to hear such things from people who recommend drinking disinfectants to ward off the coronavirus — to contend they are still a party to the agreement after officially leaving it,” said Zarif.

This appeared to refer to Trump’s suggestion for research into whether the coronavirus might be treated by injecting disinfectant into the body.

Meanwhile, a Foreign Ministry spokesman ridiculed a 2019 US State Department report released on Wednesday that Iran and four other countries had not cooperated fully with US counter-terrorism efforts.

“With a history of founding, funding and arming different terrorist groups, a record of state terrorism, and its outright support for another terrorist regime, US is not a good yardstick for measuring anti-terrorism efforts,” spokesman Abbas Mousavi tweeted.
