A fresh round of talks aimed at arranging a Gaza cease-fire in exchange for hostages held by Hamas militants is being planned for Cairo this weekend with U.S. representation, the White House said Friday.

CIA Director Bill Burns will lead the U.S. delegation, a U.S. official said.

White House national security spokesperson John Kirby said President Joe Biden told Israeli Prime Minister Benjamin Netanyahu in a phone call on Thursday to empower his negotiators in Cairo so that a deal can be reached as soon as possible.

The United States and its allies view a cease-fire as essential to allowing more humanitarian aid to get into Gaza amid fears of famine among the Palestinians there.

Under the most recent proposal, Israel and Hamas would agree to a six-week cease-fire in exchange for the release of sick, elderly and wounded hostages held by Hamas. Progress on a deal has been stalled for weeks.

"Let's get a deal in place so that we can get a cease-fire for a matter of weeks in place, so that it's easier to meet those commitments on humanitarian assistance being increased," Kirby told reporters on Friday.

Kirby said there were no plans by the United States to conduct an independent investigation into the killings of seven World Central Kitchen aid workers.

The Israeli military dismissed two officers and formally reprimanded senior commanders after an inquiry into the killing of the aid workers in a Gaza airstrike this week found serious errors and breaches of procedure.

Netanyahu had briefed Biden in their phone call on Thursday on the general findings of Israel's inquiry into the incident. Biden warned Netanyahu that Israel must take steps to address civilian harm and humanitarian suffering or else Washington will take unspecified steps in response.

Israel also announced it was opening the Ashdod port and Erez crossing to increase the flow of aid into Gaza.

Biden, asked if he had threatened to withhold military support for Israel, told reporters on Friday: “I asked them to do what they’re doing."
