What are the main elements of the Gaza ceasefire deal?

Negotiators reached a deal on Wednesday for a ceasefire in the Gaza war between Israel and Hamas, an official briefed on the negotiations told Reuters, after 15 months of conflict that has killed tens of thousands of Palestinians and inflamed the Middle East.

The details have not yet been publicly announced by the mediators, Israel or Hamas.

Here are the main elements of the ceasefire deal, according to the official briefed on the agreement:

• A six-week initial ceasefire phase includes the gradual withdrawal of Israeli forces from central Gaza and the return of displaced Palestinians to northern Gaza
• The deal requires 600 truckloads of humanitarian aid to be allowed into Gaza every day of the ceasefire, 50 of them carrying fuel, with 300 of the trucks allocated to north
• Hamas will release 33 Israeli hostages, including all women (soldiers and civilians), children, and men over 50. Hamas will release female hostages and under 19s first, followed by men over 50
• Israel will release 30 Palestinian detainees for every civilian hostage and 50 Palestinian detainees for every Israeli female soldier Hamas releases
• Israel will release all Palestinian women and children under 19 detained since October 7 2023 by end of the first phase. The total number of Palestinians released will depend on hostages released, and could be between 990 and 1,650 Palestinian detainees including men, women and children
• Hamas will release the hostages over a six-week period, with at least three hostages released each week and the remainder of the 33 before the end of the period. All living hostages will be released first, followed by the remains of dead hostages
• The implementation of the agreement will be guaranteed by Qatar, Egypt and the US
• Negotiations over a second phase of the agreement will begin by the 16th day of phase one and is expected to include the release of all remaining hostages, including Israeli male soldiers, a permanent ceasefire and the complete withdrawal of Israeli soldiers
• A third phase is expected to include the return of all remaining dead bodies and the start of Gaza's reconstruction, supervised by Egypt, Qatar and the UN.
