Yukiya Amano, the chief of the International Atomic Energy Agency (IAEA), on Tuesday reaffirmed Iran's compliance to its commitments under the 2015 nuclear deal, officially called the Joint Comprehensive Plan of Action (JCPOA).

"In my regular reports to the board I have stated that Iran is implementing those commitments," Amano insisted, Press TV reported.

"Since January 2016, the agency [IAEA] has been verifying and monitoring Iran's implementation of its nuclear-related commitments under the JCPOA," the IAEA chief added.

Amano further noted that IAEA inspectors have full access to all locations required to verify the deal's implementation.

Under the agreement, reached between Iran and the 5+1 group, Tehran undertook to put limits on its nuclear program in exchange for the removal of nuclear-related sanctions.

U.S. President Donald Trump, however, withdrew Washington from the landmark agreement last May and ordered what the U.S. described as the “toughest” sanctions ever against Tehran. The sanctions targeted Iran's banking and energy sectors with the aim of cutting off the country's oil sales and crucial exports.

Amano's remarks came as the U.S. special representative for Iran says Washington is not looking to grant any further waivers to countries importing Iranian oil.
