Vienna: The United Nations’ nuclear watchdog has stepped up pressure on Iran, calling on the country to fully explain the status of its enriched uranium and to allow inspectors complete access to its nuclear sites.

The International Atomic Energy Agency’s Board of Governors, made up of 35 member states, passed a resolution this week asking Iran to provide clear and updated information on its uranium stockpile, including material enriched close to weapons grade. The resolution was put forward by the United States, the United Kingdom, France and Germany.

According to the IAEA, Iran currently holds more than 440 kilograms of uranium enriched to around 60 percent purity. While this is below the level needed for a nuclear weapon, it is much higher than the amount typically used for civilian energy programs and is considered a short technical step from weapons grade.

Inspectors have been facing difficulties in gaining full access to some nuclear facilities, especially those damaged during airstrikes earlier this year. The agency says this has created gaps in its understanding of how much enriched material Iran currently has and where it is stored.

Iran has rejected the resolution, saying it is unfair and does not reflect the challenges it faces after several of its nuclear sites were attacked. Tehran says some inspections have already resumed under a previous agreement and insists it is cooperating where possible.

IAEA Director General Rafael Grossi confirmed that inspectors have returned to several sites in recent weeks, but added that access to the most sensitive locations is still unresolved. He said the agency needs a complete picture of Iran’s nuclear activities to ensure transparency and safety.

Western countries have warned that Iran must comply with its international commitments, while Russia and China voted against the resolution, accusing the West of creating unnecessary pressure.

The situation adds new tension to already fragile relations in the region. The coming weeks will be important as the IAEA prepares its next report and Iran decides whether to open more of its facilities to inspectors.
