At a joint press conference with European Commissioner Miguel Arias Cañete, Ali Akbar Salehi, head of the Atomic Energy Organization of Iran, said that he does not rule out the possibility that the Islamic Republic of Iran will resume uranium enrichment, Interfax reported.
"In front of us there is a choice from many possibilities; we can resume enrichment of uranium up to 20%," the official said.
"If the other side keeps itself committed to its promises, we also will keep them. Our policy is to wait for several weeks and see what happens next [after the US withdraws from the agreement]," he explained.
On May 8, US leader Donald Trump said that Washington would cancel the nuclear deal, which Iran and six mediating countries concluded in 2015 after many years of negotiations.
