Europe on Monday urged the US not to further escalate tensions over the Iran nuclear deal, with Britain issuing a stark warning of the risk of conflict erupting "by accident" in the Gulf. US Secretary of State Mike Pompeo made a last-minute change of plan scrapping an expected Moscow trip to instead visit Brussels and meet his counterparts from Britain, France and Germany. The ministers, from the European signatories to the 2015 accord that curbed Iran's nuclear ambitions in return for sanctions relief, all publicly criticised the hardline US approach.
