BRUSSELS, May 13 (Xinhua) -- The European Union (EU)'s top diplomat stressed on Monday evening that Iran is still compliant with the nuclear deal.

"I insist, so far, the IAEA (International Atomic Energy Agency) has certified that Iran is compliant," Federica Mogherini, the EU's High Representative for Foreign Affairs and Security Policy, told reporters.

"I want to stress this because I believe it is important. We reaffirmed today with the 28 Foreign Ministers of the European Union Member States that the IAEA remains the only entitled body to verify that Iran is or is not compliant with its nuclear commitments," she said.

The deal, endorsed by the United Nations Security Council, was reached in 2015 between Iran, China, France, Russia, Britain, United States, and Germany.

The U.S., under President Donald Trump, withdrew from the Iran nuclear deal, despite objections from the international community. The European signatories still support the deal and have vowed to sidestep U.S. sanctions re-imposed after its withdrawal.
