The International Atomic Energy Agency announced Friday that Iran has allowed agency inspectors to access one of two sites suspected of having undeclared nuclear activities, after a long crisis over them, at a time when Iran's stockpile of enriched uranium has increased 10 times the limit stipulated in the nuclear agreement between Iran and the Powers Major.

A report by the International Agency said that the agency searched one of the two sites and took environmental samples from there, referring to samples aimed at detecting traces of nuclear materials that may have been present.

The report said that IAEA inspectors will visit the other site later this month, at a date already agreed upon with Iran to take environmental samples.

The UN agency also announced that Iran's stockpile of enriched uranium currently exceeds 10 times the limit stipulated in the nuclear agreement that Iran concluded with major powers in 2015.

The agreement refers to a limit of 300 kilograms of enriched uranium in the form of a specific compound, equivalent to 202.8 kilograms of uranium, and the agency's report stated that the current Iranian stockpile amounts to 2,105 kilograms.

On the 26th of last month, Iran announced that it had agreed to allow the IAEA to enter two sites that the agency suspects of secretly containing nuclear materials. This reflected a breakthrough in the dispute over the two sites near Karaj and Isfahan.

The Agency's director, Rafael Mariano Grossi, also went to Iran about two weeks ago, on his first visit, to put pressure on Tehran, in the context of increasing tension between the United States and its European allies regarding Washington's attempt to extend the arms embargo imposed on Iran and re-impose international sanctions on it.

Britain, France and Germany rejected this initiative, believing that it would frustrate their efforts to save the 2015 nuclear agreement, which US President Donald Trump withdrew from his country in 2018.

Grossi said in a tweet on Twitter that he would discuss with Iranian officials the guarantees related to Iran's compliance with the nuclear agreement, expressing his hope that his meetings would open channels of communication for fruitful and constructive cooperation between Iran and the IAEA.

The agency's board of governors, which includes 35 countries, passed a resolution in June to increase pressure on Iran to allow inspectors access to the two sites listed in two of the agency's quarterly reports, as they may still contain undeclared nuclear material or remnants of it.
