As the war in Gaza enters its tenth month, a cease-fire resolution finally seems near after months of negotiations.

Sources told the Israeli media Haaretz that a deal is possible “within days” after Qatar truce talks resumed on Wednesday, where CIA director Bill Burns is meeting with senior Qatari, Egyptian and Israeli officials.

The Washington Post reports that although the framework for the cease-fire deal is in place, officials warn that a final pact may not be imminent and the details will take time to work through.

So far, Israel and Hamas have both signaled their acceptance of an “interim governance” plan that would begin with the second phase of the deal, in which neither Hamas nor Israel would govern Gaza, the Post reports. Instead, security would be provided by a force trained by the United States and supported by moderate Arab allies, drawn from a core group of about 2,500 supporters of the Palestinian Authority in Gaza who have already been vetted by Israel.

White House national security spokesperson John Kirby told CNN on Wednesday that the United States is “cautiously optimistic that things are moving in a good direction.”

“There are still gaps remaining between the two sides,” he continued, adding that the U.S. is working to narrow them.

The proposal consists of three phases. In the first, Hamas would release hostages who meet certain humanitarian criteria in exchange for the release of Palestinian prisoners. Israeli troops would withdraw from agreed-upon areas in the enclave as well as allow humanitarian aid to enter and displaced Palestinians to return to their homes. In the second phase, the details of which will be negotiated as it progresses, Israel would accept a more durable cease-fire and Hamas would release the remaining living hostages in continued exchange for other Palestinian prisoners. Gaza’s reconstruction would then begin in the third.

Israeli Prime Minister Benjamin Netanyahu has insisted the deal must not prevent Israel from resuming fighting until its war objectives, including preventing Hamas from ruling Gaza again, have been met. Hamas has conceded, dropping its demand that Israel commit to a permanent cease-fire before signing the deal.

Additionally, the Post reports that Hamas has relented on its demand for a written guarantee of a permanent end to the fighting, accepting the U.N. Security Council resolution which passed last month in lieu.

However, Hamas has warned that recent Israeli pushes deeper into Gaza City could set cease-fire and hostage release talks “back to square one.”
