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".

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.

First phase of agreement likely to involve release of 33 Israeli hostages and up to 1,000 Palestinian prisoners
