Hamas has named four hostages to be released on Saturday under the Gaza ceasefire deal.
It says they are soldiers Karina Ariev, Daniella Gilboa, Naama Levy and Liri Albag. They will be freed in exchange for 180 Palestinian prisoners held in Israel.
It will be the second such exchange since the ceasefire came into effect last Sunday.
Three hostages and 90 prisoners were released in the first swap.
Dr Ayelet Levy, whose daughter Naama Levy was taken hostage by Hamas, called her daughter "a very strong girl" when she spoke to the BBC last year
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.
This includes the Bibas family - two parents and two children, one of whom, Kfir, was 10 months old when taken captive and is the youngest hostage. It is unclear if this information will include the names or just the number of living or dead hostages.
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.
Ariev, Gilboa, Levy and Albag were seized at the Nahal Oz military base which was overrun by Hamas gunmen. Footage showed them among a group of women being tied up with their hands behind their backs. They were seen pleading for help while being taunted by their captors.
The women were part of a unit which surveilled the Israel-Gaza border.
Three weeks ago Hamas released a video of Albag, 19, calling for the Israeli government to reach a deal.
The ceasefire was concluded after months of indirect negotiations between Israel and Hamas, led by the US, Qatar and Egypt.
