Iran FM calls US resuming nuclear tests 'regressive and irresponsible'

Iran's foreign minister called on Thursday US plans to resume nuclear testing "regressive and irresponsible", after a surprise directive by US President Donald Trump.

"A nuclear-armed bully is resuming testing of atomic weapons. The same bully has been demonising Iran's peaceful nuclear program," Abbas Araghchi said in a post on social media.

"The (US) announcement of a resumption of nuclear tests is a regressive and irresponsible move and a serious threat to international peace and security," he added.
