EU foreign ministers are meeting on Monday to discuss the latest developments concerning the Iran nuclear deal. They will try to flesh out a plan to convince Iran and the United States to ease tensions amid fears it could collapse.
Tensions between the two countries have worsened since Donald Trump decided to pull out of the nuclear deal last year.
Under the nuclear deal, negotiated by the Obama administration, Iran agreed to curtail its atomic programme in return for a cut from economic sanctions.
In a joint statement issued ahead of the meeting, Britain, France and Germany reiterated their support for the deal.
But said they were “deeply troubled” by recent events in the Gulf and “concerned” over US-Iran relations.
Earlier this month Iran said it would be breaching the deal by breaking a limit set on uranium enrichment.
