Here’s a closer look at the deal between Israel and Hamas.

There is an agreement between Israel and Hamas on a temporary ceasefire is expected to come into effect on Friday. Here’s a closer look at the deal, which was partly brokered by Qatar, and how it is expected to play out.

What’s in the deal?

The agreement provides for a pause in hostilities of at least four days. During that time, at least 50 women and children – of the approximately 240 people Israeli officials say were kidnapped on October 7 – would be exchanged for 150 Palestinian women and minors held in Israeli prisons.

The deal also includes an increase in humanitarian aid for Gaza, but Qatar’s Foreign Ministry has not released details. Hamas said Thursday that 200 trucks carrying aid and four fuel trucks would enter the area each day during the four-day break. Israeli officials did not immediately comment.

Israel said its warplanes would not fly over southern Gaza for the duration of the ceasefire, nor would they fly over the northern part of the territory for six hours a day.

How is it carried out?

The break is expected to start at 7 a.m. Gaza time (midnight East) on Friday, Qatar’s Foreign Ministry spokesman Majed al-Ansari said on Thursday, which Hamas confirmed. Mr al-Ansari said an initial group of 13 hostages would then be released from 4pm in exchange for an undisclosed number of Palestinian prisoners.

Each day of the break, Israel and Hamas will receive lists of the hostages and prisoners to be released, while Qatar will pass them between the two sides, Mr al-Ansari said. He said the International Committee of the Red Cross would be designated to receive the hostages, although he gave no further details on the group’s role or where the hostages would cross the border.

The Israeli government has said that the hostages would be released during the ceasefire in four groups, each containing at least 10 people.

An Israeli official, speaking on condition of anonymity on Wednesday, said the hostages handed over by Hamas would be taken to hospitals and the seriously injured would be airlifted by helicopter. Those under 12 will be met at the border by their families, the official said, while older hostages will meet their families at hospitals, where they will also be questioned by security forces.

The official said the Palestinians to be released from Israeli prisons, most of whom are from the West Bank, will be taken by bus to their home districts. It was unclear whether they too would be released in phases, but the official said the first would be released before any Israeli hostages.

Who are the Palestinian prisoners?

The Israeli government this week published a list of 300 names – all people aged 18 and under or women – of Palestinian prisoners are being considered for release. It was not immediately known who would be among the 150 who would be released.

All names on the list were described as “security prisoners,” or people arrested in connection with crimes against national security. The prisoners are accused of supporting terrorism, violent crimes and throwing stones, among other things. There are also several charges of attempted murder. Most of the prisoners on the list had not been convicted of the charges.

There were 32 women and girls listed, including two 18-year-olds and a 15-year-old. Of the boys, 144 are 18 years old and 123 are between 14 and 17 years old.

Who are the hostages being released?

The Israeli prime minister’s office said it had received an initial list of names of the hostages to be released and had contacted their families. It was not specified how many names were on that list.

At least 36 children and teens, ranging in age from childhood to senior year of high school, are being held in Gaza, and little is known about their whereabouts or well-being. Some, but perhaps not all, are expected to be among the hostages released in the coming days.

White House officials said Tuesday that they expected the agreement would include the release of three Americans: two women and a toddler.
