Mughrabi and Maayan Lubell DOHA/CAIRO/JERUSALEM (Reuters) -Negotiators in Qatar resumed talks on Wednesday hoping to hammer out the final details of a complex, phased ceasefire in Gaza aiming to end a conflict that has inflicted widespread death and destruction and upended the Middle East.

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".

The first phase, spanning a 42-day ceasefire, would see the exchange of 33 Israeli hostages in Gaza for Palestinians held in Israeli prisons, U.S. officials said.
