Iran nuclear deal: Enriched uranium limit breached, sources say

Iran has breached a 300kg (660lb) limit on its stockpile of enriched uranium set under a 2015 nuclear deal with world powers, sources say.

In May, the country quadrupled its production of the material, which is used to make nuclear reactor fuel – and potentially nuclear weapons.

It said it was responding to sanctions reinstated by the US after President Donald Trump abandoned the deal.

European nations have warned Iran that any violation will bring consequences.
