Gazans are curbing their optimism, having experienced other times throughout the war when a cease-fire was thought to be within reach, only for it to fall apart.

Two parents and two of their sons were killed in an Israeli airstrike that hit their tent in the Mawasi area near Khan Younis. A relative told an NBC News crew that the family had been celebrating news of the ceasefire agreement days earlier.

Under the Gaza ceasefire deal, Israel has agreed to release Palestinians held in Israeli jails in return for freeing hostages taken by the militant group Hamas in their Oct. 7, 2023 attack. There is no final agreement on which prisoners will be released in return for hostages,

Outgoing Democratic U.S. President Joe Biden said on Thursday that Israeli Prime Minister Benjamin Netanyahu "has to find a way to accommodate the legitimate concerns" of Palestinians for the long term sustainability of Israel.

Marking an end to more than 15 months of deadly conflict, Israel and Hamas reached a ceasefire deal on Wednesday.

The city of Jenin in the northern West Bank has been a flashpoint in the Israeli-Palestinian conflict for decades.

In war-ravaged Gaza, many displaced Palestinians do not know if their homes are still standing, thousands are still buried under rubble and dozens are missing after encounters with Israeli forces. Vast areas appear uninhabitable, and it could take decades to rebuild.

Palestinians in the Middle East and around the world on Jan. 15 celebrated the news of a ceasefire and hostage release deal between Israel and Hamas.

More than 46,000 Palestinians were killed over the past 15 months, according to the Associated Press, citing figures from the Gaza Health Ministry. About 1,200 Israelis were killed on Oct. 7, 2023, in Hamas' attack and an additional 840 Israeli soldiers were killed. Arab American activists say the Palestinian death toll is higher than reported.

Celebrations erupted across Gaza as news spread of an imminent ceasefire announcement, with people rejoicing at the idea of more humanitarian aid coming in, and an end to Israeli airstrikes.

The first phase of the deal, which includes a series of hostage and prisoner exchanges, is taking place from today. Meanwhile, Israel PM Netanyahu has vowed to bring home all hostages held in the Palestinian territory.
