Escalation with Iran in nuclear row

The US has threatened to confront Iran at the International Atomic Energy Agency next month if it does not cooperate more with the watchdog — an escalation that could undermine talks on reviving a 2015 Joint Comprehensive Plan of Action with Iran.
Tehran is locked in several standoffs with the IAEA, whose 35-nation board of governors is holding a quarterly meeting this week.
Former US President Donald Trump pulled Washington out of the JCPOA, otherwise known as the Iran nuclear deal, that lifted sanctions on Tehran in return for restrictions on its atomic activities.
Trump reimposed debilitating sanctions, after which Tehran expanded its nuclear work and reduced cooperation with the IAEA.
