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.
Hostage release to be 'prime' focus of Blinken's Middle East trip, Kirby says
Releasing more hostages will be a "prime" focus of Secretary of State Antony Blinken's latest trip to the Middle East, the White House said.
"We're up around 70 or so hostages out so far, which is good. It's a good start, but it's just a start. There are many more," White House National Security spokesperson John Kirby told reporters Tuesday. "We want to get them all back."
Blinken will also meet with his Israeli counterparts to reassure them of U.S. support and talk about getting humanitarian assistance to Gaza, Kirby said.
This week's trip will be Blinken's fourth to the region since the Oct. 7 attack.

12 hostages released in latest exchange: IDF
Twelve hostages are back in Israeli territory in the latest exchange, according to the Israeli government.
The hostages include 10 Israelis and two foreign nationals, both from Thailand, officials said.
The Israeli citizens were identified as Tamar Metzger, 78; Ditza Hayman, 84; Norlin Babdila, 60; Ada Sagi, 75; Ophelia Edith Roitman, 77; Rimon Kirsht, 36; Merav Tal, 53; and the Leimberg family -- Gabriella Leimberg, 59, Mia Leimberg, 17, and Clara Marman, 63.
The IDF said the hostages were taken through Egypt before heading to a meeting point in Kerem Shalom, in Israel.
Five of the women -- Metzger, Hayman, Ada Sagi, Roitman and Tal -- were residents of Kibbutz Nir Oz, one of the communities hit hardest by Hamas' Oct. 7 attack.
"They were held captive, in harsh conditions and deprived of essential medical care. Two of the women released have been separated from their husbands, who remain in captivity," the kibbutz said in a statement. "The Nir Oz community is committed to support them, and their families, through the long recovery process ahead."
Thirty Palestinian prisoners were released in exchange for the hostages, according to Qatari officials.

4-year-old American-Israeli released from hospital
Abigail Idan, the 4-year-old American-Israeli hostage who was released by Hamas on Sunday, has been discharged from Schneider Children's Medical Center, hospital officials said.
"Since her arrival, the medical and psychosocial team at Schneider accorded her all-embracing medical and emotional care," officials said.
President Joe Biden said Monday that he "spoke with Abigail’s family following her release, and we are working closely with our Israeli partners to ensure she gets the care and support she needs as she begins to recover from this unspeakable trauma."
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."
