The officials, who requested anonymity to speak about the sensitive exchange, said that the plan detailed by the Israelis did not change the U.S. administration’s view that moving forward with an operation in Rafah would put too many innocent Palestinian civilians at risk.

Israeli Prime Minister Benjamin Netanyahu has vowed to carry out a military operation in Rafah despite warnings from President Joe Biden and other western officials that doing so would result in more civilian deaths and worsen an already dire humanitarian crisis.

The Biden administration has said there could be consequences for Israel should it move forward with the operation without a credible plan to safeguard civilians.

“Absent such a plan, we can’t support a major military operation going into Rafah because the damage it would do is beyond what’s acceptable,” U.S. Secretary of State Antony Blinken said late Friday at the Sedona Forum, an event in Arizona hosted by the McCain Institute.

Some 1.5 million Palestinians have sheltered in the southern Gaza city as the territory has been ravaged by the war that began on Oct. 7 .

The officials added that the evacuation plan that the Israelis briefed was not finalized and both sides agreed to keep discussing the matter.

White House press secretary Karine Jean-Pierre told reporters on Friday that no “comprehensive” plan for a potential Rafah operation has been revealed by the Israelis to the White House.

The operation, however, has been discussed during recent calls between Biden and Netanyahu as well as during recent virtual talks with top Israeli and U.S. national security officials.

“We want to make sure that those conversations continue because it is important to protect those Palestinian lives — those innocent lives,” Jean-Pierre said.

The revelation of Israel's continued push to carry out a Rafah operation came as CIA director William Burns arrived Friday in Egypt, where negotiators are trying to seal a cease-fire accord between Israel and Hamas.
