Tehran - ALsharqiya January 27: Iran threatened to stop the surprise inspections by the International Atomic Energy Agency on its nuclear facilities and demanded that Washington lift the sanctions on it before it recommits itself to the terms of the nuclear agreement that US President Joe Biden wants his country to rejoin. Iranian government spokesman Ali Rabiei said the first steps to restrict inspections related to the additional protocol would begin on February 19. US President Joe Biden had said that the United States would return to the agreement if Iran returned to abide by it. The agreement requires Iran to implement an additional protocol that provides inspectors with wide freedom of access to information about Iran's nuclear activities and the ability to inspect any site they deem necessary to inspect to verify that these activities are peaceful.
