Hamas militants freed three male hostages held for more than a year in the Gaza Strip on Saturday and Israel released 183 Palestinian prisoners from Israeli jails in the fourth such exchange of a ceasefire deal that has halted 15 months of intense fighting.

Militants handed Yarden Bibas and French-Israeli Ofer Kalderon to Red Cross officials in the southern city of Khan Younis, while American-Israeli hostage Keith Siegel, looking pale and thin, was released to the Red Cross later Saturday morning in Gaza City to the north.

All three were abducted during the Hamas-led attack on Israel on Oct. 7, 2023, that sparked the war. Their release brings to 18 the number of hostages released since the ceasefire began on Jan. 19.

The releases were quick and orderly, in contrast to chaotic scenes that unfolded on Thursday when armed militants appeared to struggle to hold back a crowd during a hostage release. In both of Saturday's releases, masked and armed militants stood in lines as the hostages walked onto a stage and waved before being led off and handed over to the Red Cross.

In Tel Aviv's Hostages Square, thousands of people gathered to watch the releases being transmitted live on a large screen, waving signs and cheering.

Shortly after Siegel arrived in Israel, a bus departed Ofer Military Prison with some 32 prisoners bound for the West Bank. Crowds of well-wishers greeted the bus, cheering and hoisting the released prisoners on their shoulders in scenes of jubilation.

The Israeli Prison Authority said all 183 Palestinian prisoners slated for release Saturday had been freed. Most, including 111 arrested after Hamas' Oct. 7, 2023 attack, were released to Gaza. Just over two dozen returned to cheering crowds in the occupied West Bank. Another seven serving life sentences were transferred to Egypt ahead of their deportation.

The ceasefire is aimed at winding down the deadliest and most destructive war ever fought between Israel and Hamas. The deal has held for two weeks, allowing for increased aid to flow into the tiny coastal territory and for hundreds of thousands of Palestinians to return to the remnants of their homes in the north of the strip.

During the truce's six-week first phase, a total of 33 Israeli hostages are to be freed in exchange for nearly 2,000 Palestinian prisoners. Israel says it has received information from Hamas that eight of those hostages were either killed in Hamas' Oct. 7, 2023, attack or have died in captivity.

Also on Saturday, a group of 50 sick and wounded Palestinian children left Gaza for treatment through the Rafah border crossing to Egypt, in the first opening of the enclave's sole exit since Israel captured it nine months ago. A European Union civilian mission was deployed Friday to prepare for the reopening.

The reopening of Rafah marked another key step in the first phase of the ceasefire.

Israel's Prime Minister's Office confirmed on Tuesday that Benjamin Netanyahu is traveling to the US to meet President Donald Trump. The leaders are likely to discuss the ceasefire agreement between Israeli forces and Hamas militants.

The meeting is reportedly scheduled for next Tuesday. Netanyahu could become the first foreign leader to visit the White House since Trump's inauguration last week. Trump and his team are working to secure the release of Americans and others still held hostage by Hamas.

Israel has released nearly 300 Palestinian prisoners as part of the agreement. Hamas says it will release 33 hostages in total. It has already freed seven Israeli women, and it says six more hostages will be released by the end of the week.

However, a spokesperson for Israel's government, David Mencer, says 25 of the hostages are alive but eight have been killed by Hamas.

The ceasefire called for Israel to lift travel restrictions in northern Gaza. Authorities there say more than 300,000 residents have already returned to the area. However, many are coming back to find their homes and communities in ruins.
