Director-General of the International Atomic Energy Agency (IAEA) Rafael Grossi called the situation around Iran's nuclear program alarming, noting that Tehran has reached such a level of uranium enrichment that only countries producing nuclear weapons have achieved, Grossi told Financial Times.

The enrichment of the country's uranium at the level of 60% is a very serious thing, only the states that produce bombs reach this level, the head of the IAEA noted. 

Qualitatively, important progress has been made, he added.

The reserves of enriched uranium in Iran at present, according to his data, are more than 10 times higher than the 300 kg limit set earlier in the agreement, TASS reported.

The development of a nuclear program for medical purposes and research is his sovereign right of Iran. True, given the current level of industrial and medical activity, we do not see a special need for this, but this should be decided by the country, he said.
