US Secretary of State Mike Pompeo accused Iran on Tuesday of "undeclared potential nuclear activities".
Pompeo wrote on Twitter that the "lack of full cooperation by the Iranian regime" with the IAEA raises "questions about possible undeclared nuclear activities or materials" in the Islamic Republic, which the IAEA has asked to answer questions about its nuclear program.
He added that "the world will not be deceived. We will deny the regime (Iranian) all the ways that may lead (to possess) a nuclear weapon."
Pompeo´s comments came a day after IAEA acting director general Cornell Verota called on Iran to respond quickly to his organization´s concerns about Tehran´s nuclear program as the Islamic Republic takes steps to reduce its commitment to the terms of the 2015 deal.
On Monday, Israeli Prime Minister Benjamin Netanyahu accused Iran of possessing and destroying a previously undisclosed site to develop nuclear weapons.
