Iran's nuclear sites have been targeted in US-Israel attacks and Iran has suspended access for International Atomic Energy Agency inspectors.

The resolution, drawn up by Britain, France, Germany and the United States, said it is "essential and urgent" that Iran "without delay" provides the IAEA with "complete information on nuclear material inventories and design information for facilities".

The resolution -- passed by 21 votes to three with 10 abstentions -- also demanded that Iran "grant the agency all access it requires to verify this information", said diplomats. One country on the 35-member board did not vote.

The IAEA estimates that Iran had 440 kilogrammes of uranium enriched to 60 percent, close to the level needed for a bomb. But inspectors have not seen the material since June 10 last year, as Israel launched its first strikes on Iran's nuclear facilities.

Iran then suspended cooperation with the watchdog and western nations say the information and access is crucial to determining whether uranium has been diverted.

The agency said in a report ahead of the board meeting that Iran's refusal to allow access was a "proliferation concern".

On Tuesday, Iran's Vienna mission posted on X that it was "ridiculous" for the United States "aggressor" to submit this "unnecessary provocative resolution".

The IAEA board adopted a resolution in November calling on Iran to cooperate with nuclear inspectors.

Since the Middle East war erupted with US-Israeli strikes on February 28, Iran has negotiated with the United States but resisted demands to give up its nuclear programme.

Western countries and Israel have long accused Iran of seeking a nuclear weapon. It denies the charge.
