European powers demanded at talks on Friday that Iran stop violating their nuclear deal, but stopped short of triggering a mechanism that could renew U.N. sanctions and kill the 2015 accord, officials said.
The meeting came amid heightened friction between Iran and the West. Tehran has rolled back its commitments under the 2015 deal in response to Washington's withdrawal last year and the reimposition of sanctions that have crippled its economy.
With Tehran angry over a lack of European protection from U.S. sanctions, there appears scant scope for compromise.
