Paris (AFP) – France, Britain and Germany on Thursday triggered a mechanism to reimpose United Nations sanctions on Iran for failing to comply with commitments over its nuclear programme.

The three countries notified the UN Security Council that they “believe Iran to be in significant non-performance of its commitments” under a 2015 nuclear deal, according to a letter seen by AFP.

Their foreign ministers said they “hereby invoke the process known as the ‘snapback’ mechanism,” which initiates a 30-day process for reimposing sanctions suspended a decade ago.
