Tehran revealed it will break through its internationally-agreed limits on the amount of low-enriched uranium it keeps in 10 days. The announcement is a threat to signatories to the Iran nuclear deal, pressuring them to ramp up action to save the agreement after the US pulled out last year. Iran's Atomic Energy Organisation spokesman Behrouz Kamalvandi said on state TV: "We have quadrupled the rate of enrichment and even increased it more recently, so that in 10 days it will bypass the 300 kg limit. "There is still time ... if European countries act." Iran said it would reduce compliance with the Iran nuclear deal, struck in 2015, in protest at Donald Trump’s decision to pull out of the agreement and reimpose sanctions last year. Tensions are at an all-time high, with the US last week accusing Iran of attacking two oil tankers in the Gulf of Oman. THIS IS A BREAKING NEWS STORY.
