U.S. Vice President Mike Pence said Washington will never allow Iran to acquire a nuclear weapon.

Speaking during the annual policy conference of pro-Israel lobby AIPA, Pence said Iran continues producing ballistic missiles and supporting terrorism.

Pence said Trump had signed waivers extending sanctions relief to Iran to give negotiators a chance to fix the nuclear deal, but would not do so again, The Times of Israel reported.

Unless the nuclear accord is revised during the upcoming months, the United States will immediately withdraw from the deal.

Iranian foreign minister Javad Zarif earlier said that the United States and the European countries are violating the terms of the nuclear deal. He first of all blamed the U.S. authorities who are pushing Europeans to mount pressure on Tehran.
