EU's Mogherini: Iran nuclear deal parties committed, though 'increasingly difficult'

The remaining parties to the Iran nuclear deal are committed to preserving the pact though it is "increasingly difficult," European Union foreign policy chief Federica Mogherini told reporters after a meeting of the parties at the United Nations.

"It is in the interests of all to remain committed to the deal, but it is becoming increasing difficult," Mogherini said.

The 2015 pact curbed Iran's disputed nuclear program in exchange for relief from sanctions, but has unraveled since the United States pulled out of it last year and acted to strangle Iran's oil trade to push it into wider security concessions.
