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.

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.

Among the dead were six women and four children, health officials said, as negotiators try to conclude a deal to end the 15-month war.
