Iran breaks nuclear deal and puts pressure on EU over sanctions
Further breaches could follow as Tehran seeks help in boosting trade with Europe
Iran has broken the terms of the nuclear deal for the first time since it was signed in 2015 in a move that will put pressure on Europe to do more to help mitigate the effect of crippling US sanctions.
The breaching of the limits on uranium stockpiles, warned of in advance by Iran, follows the US withdrawal from the deal last year, and frustration in Tehran that EU states have been unable to do more to counterbalance the effect of US sanctions.
