Negotiators were trying to hammer out the final details of a complex, phased ceasefire in Gaza on Wednesday after marathon talks in Qatar, and U.S. and Egyptian leaders promised to stay in close contact about a deal over the coming hours.

Work on an agreement that would pause months of fighting and free some hostages resumed after Hamas went silent.

The Israeli government and Hamas say that they are in the final stages of indirect talks over a deal for a ceasefire and the release of hostages held in Gaza and Palestinian prisoners held by Israel.

U.S., Qatari and Egyptian mediators shuttled between the Israeli and Hamas delegations in Doha on Tuesday, where officials said a deal to halt the war is near.

A deal could be announced as soon as Tuesday, Arab and Israeli officials said, raising hopes that some of the hostages held in Gaza will be released.
