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.
Israel's Supreme Court rejected the only appeal submitted thus far against the hostage deal, clearing the way for the deal to go through.
Israeli law requires a 24-hour waiting period after the vote before the agreement can be put into action.
It is expected that the cease-fire and the prisoner swap will begin Thursday morning.
The families of American hostages said they are "thrilled" 50 hostages are expected to be released, but added, "We are not going to rest until every single hostage is returned"
The families also said they "request an immediate update on whether our family members are alive and well."
The families thanked President Joe Biden for his work on the hostage deal, adding, "We call on all world leaders to continue prioritizing this goal."
The whereabouts of nine U.S. citizens and one U.S. permanent resident are unknown, according to White House national security adviser Jake Sullivan. He said it's unclear whether they were among the hundreds of people who were taken hostage by Hamas.
"We don't know for certain that all 10 are still alive and we’ve been honest about that -- what we know and what we don't know," Sullivan told ABC News' "Good Morning America" on Wednesday. "We know that among those 10, three are women and children -- two women one child. And we believe that those three will be among the 50 who are released."
"Until we actually see them come out, be in the arms of their loved ones, get home safely, we cannot be fully confident," he added.
Approximately 75 Palestinian women, five teenage girls and 200 boys -- mostly teenagers -- are detained in Israel, according to a spokesperson for Addameer, a group which monitors the treatment of Palestinian prisoners.
Before the Israel-Hamas war broke out on Oct. 7, about 150 Palestinian boys, as well as 30 women and girls, were in Israeli prisons, the spokesperson said.
According to the newly brokered deal, 150 Palestinian prisoners would be released by Israel in exchange for at least 50 hostages released by Hamas. The deal also includes a four-day pause in hostilities.
Jan Egeland, secretary general of the Norwegian Refugee Council, said in a statement that the planned four-day pause in hostilities "is not enough time to address the immense needs after six weeks of fighting, bloodshed, and destruction."
Egeland said the pause "must pave the way for a lasting cease-fire."
"Small shelters have housed scores of people, with little food and water and mounting health hazards. Children are traumatized, and many face a future without their parents and siblings," Egeland said. "They need urgent, long-term help. This can only happen through a sustained cease-fire."
