Hamas is expected to hand over to Israel the names of four hostages to be released on Saturday under the Gaza ceasefire deal.
It is believed that they will be soldiers and civilians, and all female.
They will be released in exchange for 180 Palestinian prisoners held in Israel.
This will be the second exchange since the ceasefire entered last Sunday. Three hostages and 90 prisoners were released in the first exchange.
The ceasefire stopped the war that began when Hamas attacked Israel on October 7, 2023. About 1,200 people were killed and 251 were taken to Gaza hostage.
The Hamas-run Health Ministry in Gaza says more than 47,200 Palestinians, the majority civilians, have been killed in Israel's offensive.
Hamas is also expected to provide information on the remaining 26 hostages scheduled to be released within the next five weeks.
This includes the Bibas family – two parents and two children, one of whom, KFIR, was 10 months old when he was captive and the youngest hostage. It is not clear whether this information will include names or the number of hostages living or dead.
The prisoners who will be released are a more dangerous category than those who were released on the first exchange. They will include those who have been killed, some of whom are serving sentences of more than 15 years.
Israel has insisted that no one who participated in the October 7 attacks will be released.
The ceasefire deal was reached after months of indirect negotiations between Israel and Hamas, led by the United States, Qatar and Egypt.
It will be implemented in three phases, with the second phase starting six weeks into the truce. About 1,900 Palestinian prisoners will be released during the first phase in exchange for 33 hostages. Israeli forces will also begin to withdraw from positions in Gaza and hundreds of thousands of displaced Palestinians will be able to return to the areas they fled.
The ceasefire aims to lead to a permanent end to the war in Gaza.
Ninety-one hostages remained on October 7, 2023 in Gaza. Fifty-seven of them are presumed by Israel to be alive. Three others – two of whom are alive – have been detained for a decade or more.
