The UN's nuclear watchdog is in discussions with the authorities in Iran following a report that inspectors had found that the Islamic republic has stepped up the level of uranium enrichment, approaching the limit required for an atomic weapon.
The financial information agency Bloomberg News has reported that inspectors of the International Atomic Energy Agency (IAEA) in Iran last week found uranium enriched to 84 percent purity. A level of 90 percent is required for use in a weapon.
