New York, Britain, France and Germany have warned Iran against any further breaches of the international nuclear deal signed in 2015, it was reported on Friday.
In New York on Thursday on the sidelines of the UN General Assembly (UNGA), the three EU signatories to the deal said they would trigger a special dispute mechanism if there were further violations, reports the BBC.
The warning was issued at a meeting with Iranian Ministers.
Iran began breaching its commitments under the deal after the US abandoned it and imposed sanctions last year.
The UN nuclear watchdog has said Iran was using banned enrichment technology.
If the dispute mechanism is triggered, the entire nuclear agreement could collapse and the UN could reinstate sanctions on Iran, which would be applied by all UN member states.
