Fourteen Israeli and three foreign hostages were released Sunday, the IDF said.
Thousands of people have died and thousands more have been injured since the militant group Hamas launched an unprecedented surprise attack on Israel on Oct. 7 and Israel retaliated with a bombing campaign and total siege of the neighboring Gaza Strip, leaving the region on the verge of all-out war.

The latest outbreak of war between Israel and Hamas, the Palestinian militant group that governs the Gaza Strip, has passed the four-month mark.
In the Gaza Strip, at least 30,228 people have been killed and 71,377 others have been wounded by Israeli forces since Oct. 7, according to Gaza's Hamas-controlled Ministry of Health.
In Israel, at least 1,200 people have been killed and 6,900 others have been injured by Hamas and other Palestinian militants since Oct. 7, according to the Israel Defense Forces.
There has also been a surge in violence in the Israeli-occupied West Bank. Israeli forces have killed at least 395 people in the territory since Oct. 7, according to the Palestinian Ministry of Health.
The ongoing war began after Hamas-led militants launched an unprecedented incursion into southern Israel from neighboring Gaza via land, sea and air. Scores of people were killed while more than 200 others were taken hostage, according to Israeli authorities. The Israeli military subsequently launched retaliatory airstrikes followed by a ground invasion of Gaza, a 140-square-mile territory where more than 2 million Palestinians have lived under a blockade imposed by Israel and supported by Egypt since Hamas came to power in 2007. Gaza, unlike Israel, has no air raid sirens or bomb shelters.
About 40 trucks carrying equipment for a Jordanian field hospital crossed from Egypt into Gaza via the Rafah border crossing on Monday, a border official told ABC News.
The convoy included 180 medics and nurses.
Health officials said the hospital will be set up in the southern Gaza city of Khan Younis.
Dozens of premature babies are expected to be transported from the war-torn Gaza Strip into neighboring Egypt on Monday to receive emergency medical treatment.
The babies arrived on Gaza's side of the Egyptian-controlled Rafah border crossing on Monday afternoon. Egyptian television footage showed Egyptian doctors moving the babies from Palestinian ambulances into mobile incubators. The infants will then be taken via Egyptian ambulances to nearby hospitals in the North Sinai province of northeastern Egypt, which shares a border with Gaza.
The Palestinian Red Crescent Society confirmed that its ambulance teams had transferred 28 premature babies to Egyptian medics at the Rafah border crossing on Monday afternoon. The process was done in coordination with the World Health Organization and the United Nations Office for the Coordination of Humanitarian Affairs, according to the Palestinian Red Crescent Society.
At least 12 of the babies who are said to be in deteriorating condition will be airlifted to Egypt's capital, Cairo, according to Egyptian media.
Rick Brennan, regional emergency director for the WHO's Regional Office for the Eastern Mediterranean, said in a statement, "We are cautiously optimistic that they will do well but we have to watch them very, very closely. They can still develop further complications. ... They are not out of the woods yet by any means. So they will need that intensive care for some time to come."
Three babies were in stable condition and didn't need to be transferred to Egypt for more treatment, according to the World Health Organization.
Earlier Monday, Egyptian TV footage showed medics with incubators at the Rafah border crossing as they prepared to receive the tiny patients. Egypt's heath minister was also seen on site inspecting the preparations.
The babies were evacuated on Sunday from Gaza's largest medical complex, Al-Shifa Hospital in Gaza City, and brought to Emirati Hospital in Rafah, a city in southern Gaza close to the border with Egypt.
Like many hospitals in Gaza, Al-Shifa has been struggling to function with a lack of electricity as well as limited fuel and medical supplies amid Israel's continued bombardment of the territory. In recent days, Israeli ground troops have been carrying out a raid at Al-Shifa Hospital, searching for evidence that Gaza's militant rulers, Hamas, were using the complex as a command center. The WHO described Al-Shifa Hospital as a "death zone" and urged a full evacuation after leading an assessment mission there on Sunday.

The Israel Defense Forces and the Israel Securities Authority announced in a joint statement Monday that their troops have killed three more Hamas commanders while continuing ground operations in the Gaza Strip.
"IDF fighter jets, directed by IDF and ISA intelligence, killed three additional Hamas company commanders," the statement read in part. "In addition, IDF troops identified a terrorist cell as they entered a nearby building. As a result of the strike carried out by an IDF aircraft, the terrorists were killed and a weapons depot in which they hid was struck."
There was no immediate confirmation or comment from Hamas.

Israel Defense Forces troops exposed a 180-foot tunnel 32 feet deep underneath the Shifa Hospital, the IDF and Israel Securities Authority (ISA) said in a joint statement Sunday.
"A deep staircase leads to the entrance of the tunnel shaft, which consists of various defense means including a blast-proof door and a firing hole," the statement continues. "This type of door is used by the Hamas terrorist organization to block Israeli forces from entering the command centers and the underground assets belonging to Hamas. The tunnel shaft was uncovered in the area of the hospital underneath a shed alongside a vehicle containing numerous weapons including RPGs, explosives and Kalashnikov rifles.
"IDF and ISA forces are continuing to uncover the route of the tunnel," the statement adds.
The IDF said it expects to find more tunnels and underground facilities, and that the operation is ongoing and will take some time. About 300 people remain in the hospital, according to the IDF.
