Factbox-What we know about the Gaza hostage and prisoner exchange

JERUSALEM (Reuters) - The ceasefire agreement between Israel and the Palestinian militant group Hamas is due to take effect from 8.30 a.m. (0630 GMT) on Sunday, following final approval of the deal by the Israeli government.

Thirty-three of the 98 remaining Israeli hostages, including women, children, men over 50 and ill and wounded captives, are to be freed over the course of the first phase of the ceasefire, due to last six weeks. Israel believes most are still alive but has received no confirmation from Hamas.

In return, Israel will release almost 2,000 Palestinians from its jails.

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 of 1,167 Palestinians detained in Gaza since the start of the war and held in Israel.

Israel's Justice Ministry published their details early on Saturday, along with the ceasefire agreement, which said 30 Palestinian prisoners would be released for each female hostage on Sunday.

During the first phase of the ceasefire, 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.

A second phase, exchanging the remaining hostages and completing the withdrawal of Israeli troops from Gaza is expected to follow, depending on the results of negotiations, which will begin 16 days from the start of the ceasefire.

HOSTAGE AND PRISONER HANDOVER

On Sunday after 4 p.m. (1400 GMT), Israel will hand over 95 Palestinian prisoners and will receive three hostages in exchange. The prisoners to be released on the first day of the ceasefire do not include any prominent detainees, and many were recently detained and not tried or convicted.

The identity of the three hostages to be handed over is not yet known. The military says it will publish the names once they have received the hostages.

WHAT WILL HAPPEN WHEN THEY ARE HANDED OVER?

The hostages will be handed by Hamas to Red Cross officials who will take them to the Israeli military in Gaza. The military has set up three locations near the northern, central and southern edges of Gaza in Erez, Re'im and Kerem Shalom to take charge of the hostages, according to the route they take out.

The hostages will be met there by medical staff, welfare specialists and psychologists to help with the initial transition before they are reunited with their families.

They will be taken by vehicle or helicopter to specialised facilities set up to receive them and help them adjust to returning from the trauma of 15 months in captivity. They will be kept away from the press and will receive medical and psychological support.
