Hamas has handed over another 13 Israeli hostages - six women and seven children and teenagers - as well as four Thai nationals to the Red Cross.
Among those released is nine-year-old Irish-Israeli girl Emily Hand, according to the Irish Foreign Affairs Minister Micheal Martin.
The Israeli military confirmed its hostage deal with Hamas was going ahead on Saturday after high-level diplomacy defused an aid row that threatened to derail the handover.
Israel is reported to be exchanging 39 imprisoned Palestinians for the hostages who were taken across the border from Gaza to Egypt before arriving in Israel.
The Israeli Defence Force (IDF) said the hostages would be taken "to Israeli hospitals, where they will be reunited with their families".
In a social media post, it added: "We have been preparing to welcome our people home and accompany them and their families.
"We remain determined to return all of our hostages home."
Representatives from the @ICRC just transferred 17 hostages via Egypt, including 13 Israeli and 4 Thai hostages, to ISA and IDF Special Forces, as they make their way to Israeli hospitals, where they will be reunited with their families.

Most of the released hostages were from Kibbutz Be'eri, a community Hamas militants ravaged during their October 7 cross-border attack, a spokesperson for the kibbutz said.
The children ranged in age from 3 to 16, and the women ranged from 18 to 67.A kibbutz spokesperson said all the released hostages either had a family member killed in the attack or had left a loved one in captivity in Gaza.The mother of one of the released hostages, 12-year-old Hila Rotem, remained in captivity, the spokesperson said.
It emerged earlier that US President Joe Biden spoke to the Emir of Qatar to discuss how to increase the flow of aid into Gaza, the implementation of the current truce and the hostage deadlock.
The Turkish government is also reported to have been involved in talks to free the hostages while Qatari diplomats visited Israel on Saturday to discuss a possible extension of the truce.
A Palestinian official familiar with the diplomacy said Hamas would continue with the four-day truce agreed with Israel, the first break in fighting in seven weeks of war.
It comes after Hamas said it had delayed Saturday's scheduled second round of hostage releases until Israel committed to allowing aid trucks to enter northern Gaza.
Its military wing said releases would be delayed if Israel did not adhere to the agreed terms for the release of Palestinian prisoners.
A Hamas spokesman said 340 aid trucks entered Gaza yesterday with 65 reaching Northern Gaza which he said was less than half of what Israel agreed.
The setback came just hours after Egypt, which controls the Rafah border crossing into southern Gaza through which vital aid supplies have resumed, said it had received "positive signals" from all parties over a possible extension of that deal.
The exchange comes on the second day of a ceasefire that has allowed critical humanitarian aid into the Gaza Strip and given civilians their first respite after seven weeks of war.
On the first day of the four-day ceasefire, Hamas released 24 of the about 240 hostages taken during its attack on Israel on October 7 that triggered the war, and Israel freed 39 Palestinians from prison.
Those freed from captivity in Gaza were 13 Israelis, 10 Thais and a Filipino.
During the four days of the ceasefire, Hamas is due to release at least 50 Israeli hostages, and Israel will free 150 Palestinian prisoners.
Israel has said the truce can be extended an extra day for every additional 10 hostages freed - something United States President Joe Biden said he hoped would come to pass.
Separately, a Qatari delegation arrived in Israel on Saturday to co-ordinate with parties on the ground and "ensure the deal continues to move smoothly", according to a diplomat briefed on the visit.
The start of the truce on Friday morning brought the first moment of quiet for 2.3 million Palestinians reeling and desperate from relentless Israeli bombardment that has killed thousands, driven three quarters of the population from their homes and levelled residential areas.
Rocket fire from Gaza militants into Israel went silent as well.
For Emad Abu Hajer, a resident of the Jabaliya refugee camp in the Gaza City area, the pause meant he could again search through the rubble of his home, which was flattened in an Israeli attack last week.
He found the bodies of a cousin and nephew, bringing the death toll in the attack to 19. With his sister and two other relatives still missing, he resumed his digging on Saturday.
"We want to find them and bury them in dignity," he said.
The United Nations said the pause enabled it to scale up the delivery of food, water and medicine to the largest volume since the resumption of humanitarian aid convoys on October 21.
It was also able to deliver 34,078 gallons of fuel - just over 10% of the daily pre-war volume - as well as cooking gas.
In the southern city of Khan Younis on Saturday, a long line of people with fuel cans and other containers waited outside a filling station hoping to get some of the newly delivered fuel.
For the first time in more than a month, aid reached northern Gaza, the focus of Israel's ground offensive. A UN convoy delivered flour to two facilities sheltering people displaced by fighting.
The UN said it and the Palestinian Red Crescent Society were also able to evacuate 40 patients and family members from a hospital in Gaza City, where much of the fighting has taken place, to a hospital in Khan Younis.
The relief brought by the ceasefire has been tempered, however, for both sides - among Israelis by the fact that not all hostages will be freed and among Palestinians by the brevity of the pause. The short truce leaves Gaza mired in a humanitarian crisis and under the threat that fighting could soon resume.
Israel has vowed to resume its massive offensive once the truce ends. That has clouded hopes that the deal could eventually help wind down the conflict, which has fuelled a surge of violence in the occupied West Bank.
After nightfall on Friday, a line of ambulances emerged from Gaza through the Rafah Crossing into Egypt carrying the freed hostages. The freed Israelis included nine women and four children aged nine and under.
The released hostages were taken to three Israeli hospitals for observation. The Schneider Children's Medical Centre said it was treating eight Israelis - four children and four women - and that all appeared to be in good physical condition.
It said they were also receiving psychological treatment, adding that "these are sensitive moments" for the families.
At a plaza dubbed Hostages Square in Tel Aviv, a crowd of Israelis celebrated at the news.
Yael Adar spotted her mother, 85-year-old Yaffa Adar, in a TV broadcast of the release and was cheered to see her walking.
"That was a huge concern, what would happen to her health during these almost two months," she told Israel's Channel 12.
But Yael's 38-year-old son, Tamir Adar, remains in captivity. Both were kidnapped on October 7 from Kibbutz Nir Oz. "Everyone needs to come back. It's happiness locked up in grief," she said.
The hostages included multiple generations. Nine-year-old Ohad Munder-Zichri was freed along with his mother, Keren Munder, and grandmother, Ruti Munder.
The boy was abducted during a holiday visit to his grandparents at the kibbutz where about 80 people - nearly a quarter of all residents of the small community - are believed to have been taken from.
The plight of the hostages has raised anger among some families that the government of Prime Minister Benjamin Netanyahu was not doing enough to bring them home.
Hours later, 24 Palestinian women and 15 teenage boys held in Israeli prisons in the occupied West Bank and east Jerusalem were freed. In the West Bank town of Beitunia, hundreds of Palestinians poured out of their homes to celebrate, honking horns and setting off fireworks that lit up the night sky.
The teenagers had been jailed for minor offences such as throwing stones. The women included several convicted of trying to stab Israeli soldiers, and others who had been arrested at checkpoints in the West Bank.
"It's a happiness tainted with sorrow because our release from prison came at the cost of the lives of martyrs and the innocence of children," said one released Palestinian prisoner, Aseel Munir al-Titi.
The war erupted when several thousand Hamas militants stormed into southern Israel, killing some 1,200 people, mostly civilians, and taking scores of hostages, including babies, women and older adults, as well as soldiers.
Majed al-Ansari, a spokesperson for the Foreign Ministry of Qatar, said the hope is that momentum from the deal will lead to an end to the violence. Qatar served as a mediator along with the US and Egypt.
But hours before it came into effect, Israeli defence minister Yoav Gallant told troops that their respite would be short and that the war would resume with intensity for at least two more months.
Mr Netanyahu has also vowed to continue the war to destroy Hamas's military capabilities, end its 16-year rule in Gaza and return all the hostages.
The Israeli offensive has killed more than 13,300 Palestinians, according to the Health Ministry in the Hamas-run Gaza government.
Women and children have consistently made up around two thirds of the dead, though the latest number was not broken down. The figure does not include updated numbers from hospitals in the north, where communications have broken down.
The ministry says some 6,000 people have been reported missing, feared buried under rubble. The ministry does not differentiate between civilians and militants in its death tolls.
Israel says it has killed thousands of Hamas fighters, without presenting evidence for its count.
