Iran nuclear deal parties committed, though 'increasingly difficult' -EU envoy

UNITED NATIONS, Sept 25 (Reuters) - 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. She said all parties had agreed to continue efforts to implement the deal, which U.S. President Donald Trump withdrew from in May 2018.
