With many outstanding files faltering, the Director of the International Atomic Agency, Rafael Grossi, announced that negotiations with Iran to revive the nuclear agreement had reached an impasse.

In an interview with Al-Arabiya on Tuesday, the IAEA chief said that the agency is now seeking to clarify some facts in Iran, noting that it had not received any answers to technical questions it had posed to Tehran.

He also continued that Iran had not responded to the three traces of uranium found in secret sites, stressing the need to provide precise details because verification and inspection are essential parts of the agency's work in Iranian nuclear facilities.

He also pointed out that the cameras that Iran removed were an important part of the oversight mechanism, stressing that by doing so, they undermined the agency's work and restricted transparency.

He also saw that escalation does not serve any party in the nuclear negotiations with Iran, explaining that nuclear violations keep Tehran away from the negotiation track.

As for the Karaj facility, he saw the cameras damaged, stressing that the agency does not know what happened there.

Karaj includes a number of sensitive sites, such as a workshop for spare parts for centrifuges (used to enrich uranium) in the Tissa Karaj complex, which was sabotaged last June.

The agency's announcement came today after Iran blocked two surveillance cameras belonging to the International Atomic Energy Agency at one of its nuclear sites.

It announced last week that it had suspended at least two cameras belonging to the International Atomic Energy Agency to monitor its nuclear activities after Western countries presented a draft resolution condemning it before the UN agency's Board of Governors.

It is noteworthy that the Vienna talks, launched in April 2021 to revive the nuclear agreement, had been suspended since last March after a number of issues failed to resolve.

The situation has worsened further after the United Nations' International Atomic Energy Agency issued last week a US-European resolution officially criticizing Iran for its lack of cooperation, after a previous report last month in which the agency confirmed that it had not obtained "clarifications" regarding traces of enriched uranium found in three unauthorized sites. 

Tehran responded to the agency's decision to close 27 cameras dedicated to monitoring its nuclear activities last Wednesday.
