U.S. President Joe Biden spoke with Israeli Prime Minister Yair Lapid on Wednesday, a White House official said, as Tehran seeks stronger guarantees from Washington for the revival of a 2015 nuclear deal that is strongly opposed by Israel.

In its own readout of the leaders' call, Lapid's office said they "spoke at length about the negotiations on a nuclear agreement, and their shared commitment to stopping Iran's progress towards a nuclear weapon."
