"Iran is subject to the world's most robust nuclear verification regime under the JCPOA, which is a significant verification gain," International Atomic Energy Agency (IAEA) chief Yukiya Amano said in a statement, using the deal's official name, the Joint Comprehensive Plan of Action, Reuters reported.
"As of today, the IAEA can confirm that the nuclear-related commitments are being implemented by Iran," he said, adding that the IAEA was "closely monitoring developments" related to the deal.
In a speech from the White House on Tuesday night, US President Donald Trump accused Iran of sponsoring terrorism and seeking nukes before announcing the US withdrawal from the nuclear deal.
Following the controversial decision, Iranian President Hassan Rouhani said Iran weighs plans to remain in the agreement with the other five parties, namely Russia, China, Britain, France and Germany, provided that the remaining JCPOA parties ensure its full benefits for Iran.
