PARIS/BRUSSELS (REUTERS) - France, Britain and Germany have sent an official diplomatic warning to Iran about the serious consequences Teheran faces if it scales back its compliance with the 2015 nuclear deal, two European diplomats said on Monday (June 24).

Three diplomats said the European signatories to the deal lodged the diplomatic demarche, the term for a formal note, on June 22, with two saying the communication aimed to warn Iran specifically against scaling back its commitments to the accord.

It was not immediately clear what consequences Iran might face for non-compliance.

Iran has said it will not give the European powers more time beyond July 8 to save the nuclear deal. It has said it is ready to go through with a threat to enrich uranium to a higher level if Europe cannot shield Teheran from US sanctions.
