U.S. President Joe Biden spoke on Sunday with Israeli Prime Minister Benjamin Netanyahu, the White House said, as U.S. officials race to reach a Gaza hostage and ceasefire deal before Biden leaves office on Jan. 20.

Biden and Netanyahu discussed efforts underway to reach a deal to halt the fighting in the Palestinian enclave and free the remaining hostages there, the White House said in a statement after the two leaders spoke by telephone.

Biden “stressed the immediate need for a ceasefire in Gaza and return of the hostages with a surge in humanitarian aid enabled by a stoppage in the fighting under the deal,” it said.
