The UN nuclear watchdog’s 35-nation Board of Governors has passed a US-backed resolution ordering Iran to declare its remaining enriched uranium stocks and let inspectors verify them, which could complicate Washington’s talks with Tehran, Reuters reports.

Israeli and US attacks in June last year destroyed or badly damaged Iranian uranium-enrichment plants, but much of the enriched uranium they produced, including material close to weapons-grade, is thought to have survived.

Iran still has not informed the International Atomic Energy Agency of the fate of that material, or let IAEA inspectors return to the bombed sites to check.

The resolution text submitted by the United States, the United Kingdom, France and Germany was passed with 21 votes in favour, three against and 10 abstentions, diplomats at the closed-door meeting say.

The countries opposing were Russia, China and Niger, while Venezuela was not allowed to take part, they add.
