Israel is waiting for Hamas to release the names of the next four hostages that will be freed on Saturday as part of the fragile ceasefire agreement in the Gaza war.
It is thought they will be soldiers and civilians, all female.
They will be freed in exchange for 180 Palestinian prisoners held in Israel.
It will be the second exchange since the ceasefire came into effect last Sunday. Three hostages and 90 prisoners were released in the first swap.
Speaking to the media on Thursday, Hamas official Zaher Jabarin said, “Tomorrow we will give the mediators the names of the four hostages who will be released.”
The 33 hostages to be released will include women, children, sick people and those over 50 — almost all civilians, but the deal also commits Hamas to freeing all living female soldiers.
As part of the first phase of the Gaza ceasefire 33 hostages are set to be released by Hamas over the coming weeks in exchange for hundreds of Palestinians in Israeli jails.
The ceasefire halted the war which began when Hamas attacked Israel on 7 October 2023. About 1,200 people were killed and 251 taken back to Gaza as hostages.
More than 47,200 Palestinians, the majority civilians, have been killed in Israel’s offensive, Gaza’s Hamas-run health ministry says.
Hamas is also expected to provide information about the remaining 26 hostages due to be released over the next five weeks.
The prisoners who will be released are of a more serious category than those freed in the first exchange. They will include those who have killed, some of whom are serving sentences of more than 15 years.
Israel has insisted that no-one who was involved in the 7 October attacks will be freed.
The ceasefire deal was reached after months of indirect negotiations between Israel and Hamas, led by the US, Qatar and Egypt.
