France warns Iran of violating nuclear commitments - foreign minister

France's foreign minister warned Iran on Tuesday that a violation of the 2015 nuclear deal would be a serious mistake and that France, Britain and Germany were working to ensure Tehran understood it was not in their interest to do so.

"An Iranian violation would be a serious mistake and a bad response to the pressure exerted by the United States," Jean-Yves Le Drian told lawmakers.

He added that France, Germany and Britain were totally mobilised to tell Iran that it was not in its interest to break its nuclear commitments and that the Europeans were working together to de-escalate the situation.
