“The lack of cooperation between the Iranian regime and the IAEA raises questions about possible undeclared nuclear materials or undeclared activities,” Pompeo wrote on Twitter.

According to him, this "fits into the 40-year-old Iranian scheme of lies."

“But the world will not fall for this bait. We will cut off the regime’s all paths to nuclear weapons, ”said the Secretary of State.

Earlier, US Presidential Advisor on National Security John Bolton said that Washington intends to receive a full report on the possible suspicious activities of Tehran in the nuclear program.

On September 8, the acting head of the IAEA, Cornel Feruta, arrived in Iran.
