"These are very serious discussions and negotiations and we hope that they lead somewhere," National Security Council spokesman John Kirby told reporters aboard Air Force One.

Meanwhile, Secretary of State Antony Blinken expressed hope Wednesday that the United States would be able to support a new UN Security Council resolution on Gaza.

"We've been working this intensely. I've been on the phones about this for the last couple of days," Blinken said.

"I hope we can get to a good place," he said.
