evidence: Iran continues to increase its stockpile of enriched uranium in violation of limitations set in a landmark deal with world powers, but has begun providing access to sites where it was suspected of having stored or used undeclared nuclear material and possibly conducted nuclear-related activities, the UN's atomic watchdog agency said Friday. The International Atomic Energy Agency (IAEA) said Iran's enriched uranium stockpile had reached 2,105kg (4,640lb) - well above the 300kg agreed in 2015. [...] Before agreeing to the nuclear deal, however, Iran enriched its uranium up to 20 per cent purity, which is just a short technical step away from the weapons-grade level of 90 per cent. In 2013, Iran's stockpile of enriched uranium was already more than 7,000 kilograms (7.72 tonnes) with higher enrichment, but it didn't pursue a bomb.
