Mughrabi and Maayan Lubell DOHA/CAIRO/JERUSALEM (Reuters) - Negotiators were trying to hammer out the final details of a 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 terms of a deal between Israel and Hamas for a ceasefire in Gaza and the release of hostages are being finalised, a Palestinian official familiar with the negotiations has told the BBC. It comes as White House National Security Advisor Jake Sullivan said a truce and hostage deal could be done "this week".

Mediator Qatar said on Tuesday that a Gaza ceasefire deal between Israel and Palestinian militant group Hamas is closer than at any time in the past, as the Israelis also expressed optimism over the release of hostages.
