Israel-Gaza updates: Israel says ground operation underway in southern Gaza
The IDF said it's carried out 10,000 airstrikes in the Gaza Strip.
The temporary cease-fire between Hamas and Israel ended early Friday, 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.

What we know about the conflict
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.
Hundreds of Americans, Canadians approved to leave Gaza
Over 600 foreign passport holders -- nearly half of whom are Americans and Canadians -- were on a list of people approved to leave Gaza on Sunday. Some 566 foreign passport holders, whose nationalities were not released, later exited the Gaza Strip through Egypt’s Rafah border crossing on Sunday, crossing spokesman Wael Abu Omar told ABC News.
Thirteen wounded Gaza residents and 11 of their family members also left Gaza and entered Egypt on Sunday, the spokesman said.

Israel says it's started 'powerful' ground operation in southern Gaza
The Israel Defense Forces has started a ground operation in southern Gaza that "will be no less powerful than" the operations in northern Gaza, IDF Chief of Staff Lt. Gen. Herzi Halevi said.
"We have the capabilities to do it in the most thorough way, and just as we did it with strength and thoroughly in the north of the Gaza Strip, we are also doing it now in the south of the Gaza Strip, and we also continue to deepen the achievements in the north of the Gaza Strip," Halevi said.
The IDF said it's carried out 10,000 airstrikes in the Gaza Strip since fighting began.
"The forces ‘closed circles’ and thwarted terror cells, terror infrastructure, operational apartments, tunnel shafts, weapons warehouses and more,” the IDF said in a statement.

'About 8' Americans remain hostage: Kirby
With the temporary Israel-Hamas cease-fire now over, National Security Council spokesman John Kirby told ABC News' "This Week" that the U.S. is "working at this literally by the hour … if we can get these discussions back going" to get a new pause in place.
Kirby said the Israel-Hamas agreement "fell apart because Hamas was unwilling and refused to come with additional [hostage] lists of women and children -- which we know they are holding -- and put them on the list so that Israel can evaluate that and we can get them exchanged."
Kirby said the U.S. thinks "about eight" Americans remain hostage.
He added, "We don’t have perfect visibility on where they all are, we certainly don’t have perfect visibility on their physical or mental condition."
When asked Sunday about The New York Times report alleging Israel knew about Hamas' attack plan a year in advance, Kirby said the U.S. had no knowledge of the Hamas planning document.
He added, "The focus has got to be on making sure Israel has what it needs to go after Hamas leadership."
Record amount of fuel enters Gaza
The United Nations said 138,000 liters of fuel entered Gaza on Saturday -- the highest amount in one day since the Israel-Hamas war began.
Trucks with food, water, medicine and medical supplies also entered Gaza on Saturday, according to the U.N. Office for the Coordination of Humanitarian Affairs.
Hamas claims 3 hostages, including 10-month-old, were killed by previous Israeli strikes on Gaza
Hamas' military wing al-Qassam Brigades alleged Wednesday that three hostages have died as a result of the Israeli military's previous bombings in the Gaza Strip.
In a statement posted on a Telegram channel associated with the al-Qassam Brigades, the slain hostages were identified as Shiri Silverman Bibas, Kfir Bibas and Ariel Bibas. It was unclear when the trio had allegedly died and ABC News was unable to verify the claim.
Several members of the Bibas family, including 32-year-old Shiri, her 4-year-old son Ariel and her 10-month-old son Kfir, were kidnapped from their kibbutz in southern Israel during Hamas' attack on Oct. 7 and taken hostage to Gaza, according to relatives and Israeli authorities.
The Israel Defense Forces confirmed in a statement Wednesday that it is investigating the reports of their deaths.
"IDF representatives spoke with the Bibas family following the recent reports and are with them at this difficult time. The IDF is assessing the accuracy of the information," the IDF said. "Hamas is wholly responsible for the security of all hostages in the Gaza Strip. Hamas must be held accountable."
In a statement obtained by ABC News, the Bibas family said Wednesday that they are "updated on the latest Hamas publication."
"We are waiting for the news to be confirmed or hopefully refuted soon by military officials," the family added. "We thank the people of Israel for the warm embrace but ask to maintain our privacy at this complex time."
