Iran's stock of uranium enriched to up to 60%, close to weapons-grade, has grown to well above the amount that by one definition is enough, if enriched further, for a nuclear bomb, a quarterly report by the U.N. atomic watchdog showed on Wednesday.
Iran's uranium enriched to up to 60% and in the form of uranium hexafluoride, the gas that centrifuges enrich, is estimated to have grown by 12.5 kg to 55.6 kg since the last quarterly International Atomic Energy Agency report issued on May 30, the IAEA report to member states seen by Reuters said.
At the same time, as in previous quarters, the IAEA issued a second report saying Iran had still not provided credible answers on the origin of uranium particles found at three undeclared sites that appear to mainly be old and which the IAEA has been investigating for years.
"The Director General is increasingly concerned that Iran has not engaged with the Agency on the outstanding safeguards issues during this reporting period and, therefore, that there has been no progress towards resolving them," the second report, also seen by Reuters, said.
