The Israeli army said it destroyed a key hideout for Hamas leader Yahya Sinwar.
The temporary cease-fire between Hamas and Israel ended on Dec. 1, and Israel has resumed its bombardment of Gaza.
The end of the cease-fire came after Hamas freed over 100 of the more than 200 people its militants took hostage during the Oct. 7 surprise attack on Israel. In exchange, Israel released more than 200 Palestinians from Israeli prisons.

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 80,000 vials of the measles mumps and rubella vaccine, also called the MMR vaccine, have been delivered to Gaza, according to the United Nations Relief and Works Agency for Palestine Refugees in the Near East.
The MMR vaccine is routinely given to children starting at 12 months old to 15 months old and again at 4 years old to 6 years old.
Israeli Minister for Strategic Affairs Ron Dermer, a key ally of Israeli Prime Minister Benjamin Netanyahu, will meet with Secretary of State Antony Blinken and national security adviser Jake Sullivan at the White House on Tuesday afternoon, according to administration officials.
The meeting will cover "a number of matters related to the conflict in Gaza and the return of hostages held by Hamas," according to National Security Council spokesperson Adrienne Watson.
Dermer was the Israeli ambassador to the U.S. from 2013 to 2021. He now serves in Netanyahu's government and is considered a close adviser to the prime minister.

On Christmas Day, 60 trucks crossed into Gaza via Egypt's Rafah border crossing, and an additional 60 trucks entered Gaza through Israel’s Kerem Shalom crossing, said Wael Abu Omar, the Palestinian spokesman for the Rafah crossing.
On Christmas Eve, the Royal Jordanian Air Force conducted its seventh airdrop of humanitarian aid into Gaza, the U.S. Embassy of Jordan said.
Israeli Defense Minister Yoav Gallant, in a special discussion of the Foreign Affairs and Defense Committee, said Israel is "under attack from seven different sectors: Gaza, Lebanon, Syria, Judea and Samaria, Iraq, Yemen and Iran."
"We have already reacted and acted in six of them. And I say this in the most explicit way: Anyone who acts against us is a potential target," Gallant warned. "There is no immunity for anyone."
