Iran denies seeking a nuclear weapon and says all its activities are peaceful. The IAEA counters that no country has enriched to that level without going on to build a bomb.
A senior European diplomat told Reuters last week that the level of Iran’s violations was “unprecedented”.
“There is no slowing down of its programme and there is no real goodwill by Iran to cooperate with the IAEA,” the diplomat said. “All our indicators are flashing red.”
A rift between the US and the “E3” powers of Britain, France and Germany about how to respond has been growing for months.
In November 2022, they all backed an IAEA resolution censuring Iran, but the US cautioned the E3 against a repeat at the last quarterly meeting in March.
Mohammad Mokhber, who took over as acting president on Mr Raisi’s death, addressed parliament in Tehran for the first time on Monday.
Nasser Kanaani, a spokesman for the Iranian foreign ministry, said Mr Raisi’s death had not changed Iran’s approach to getting US sanctions lifted.
