TEHRAN, Iran (AP) — Iran's President Hassan Rouhani says European nations are failing to implement their commitments following the U.S. pullout from the 2015 nuclear deal with Tehran.

Iranian state TV quoted Rouhani on Tuesday as saying that the Europeans "did not carry out their task."

The comments come as Iranian diplomats are in France for last-minute talks. Rouhani reiterated that Iran will not enter talks with the United States unless Washington lifts its sanctions against Tehran first.

Iran on Monday threatened to "take a strong step" away from the deal if Europe cannot offer new terms by a deadline at the end of this week.

Iran's oil exports have been curbed and its economy has faced freefall following crushing U.S. sanctions that imposed after President Donald Trump withdrew the U.S. from the deal.
