The head of the UN agency monitoring Iran’s compliance with nuclear deal said today that Tehran is implementing the agreement—but says the ultimate judgement on compliance with the deal rests with the six world powers that signed the pact with the Islamic Republic.

Yukiya Amano of the International Atomic Energy Agency told the 35-nation IAEA board that the terms Iran accepted “are being implemented”—an assessment that comes as members of the US administration argue otherwise.

The US administration has faced two 90-day certification deadlines to state whether Iran was meeting the conditions needed to continue enjoying sanctions relief under the deal and has both times backed away from a showdown.

But US President Donald Trump more recently has said he does not expect to certify Iran’s compliance again. The next deadline is in mid-October.
