Ammon News - A ceasefire in Gaza between Israel and Hamas is set to come into effect on Sunday morning with a hostage release to follow hours later, opening the way to a possible end to a 15-month war that has upended the Middle East.

Israeli forces started withdrawing from areas in Gaza's Rafah to the Philadelphi corridor along the border between Egypt and Gaza, pro-Hamas media reported early on Sunday.

The ceasefire agreement followed months of on-off negotiations brokered by Egypt, Qatar and the United States, and came just ahead of the Jan. 20 inauguration of U.S. President-elect Donald Trump.

The three-stage ceasefire will come into effect at 06:30 GMT (8:30 am) on Sunday.

Its first stage will last six weeks, during which 33 of the remaining 98 hostages - women, children, men over 50, the ill and wounded - will be released in return for almost 2,000 Palestinian prisoners and detainees.

They include 737 male, female and teen-aged prisoners, some of whom are members of militant groups convicted of attacks that killed dozens of Israelis, as well as hundreds of Palestinians from Gaza in detention since the start of the war.

Three female hostages are expected to be released on Sunday afternoon through the Red Cross, in return for 30 prisoners each.

After Sunday's hostage release, lead U.S. negotiator Brett McGurk said, the accord calls for four more female hostages to be freed after seven days, followed by the release of three further hostages every seven days thereafter.

During the first phase the Israeli army will pull back from some of its positions in Gaza and Palestinians displaced from areas in northern Gaza will be allowed to return. Reuters
