The EU, UK, France and Germany have expressed great concern with Iran’s latest announcement that they would immediately stop the sales of enriched uranium and heavy water, breaking two commitments under the 2015 international accord.

The ultimatum was delivered by Iran’s President Hassan Rouhani, who called on the international partners of the 2015 Iran Deal to fulfill their commitment to protect Iran's banking and oil sectors from US sanctions.

European powers have said they remain committed to the Iran nuclear deal but that they "reject any ultimatums" from Tehran to prevent its collapse.
