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."
US to send relief flights to Egypt with aid for Gaza
The United States will send three relief flights into Egypt on Tuesday to keep up the flow of humanitarian aid into the war-torn Gaza Strip, which has reached its highest levels as officials take advantage of the current humanitarian pause.
"The movement over the last four or five days of assistance has been so significant in volume that a backfill in El Arish [International Airport in Egypt] is now needed, and these planes are part of that backfill," a senior Biden administration official told reporters during a telephone call on Monday afternoon.
Some 800 trucks carrying aid have crossed into Gaza during the first days of the pause, officials said, which is a huge increase from the days prior. So far, a total of about 2,000 aid trucks have entered Gaza since Oct. 7, meaning that 40% of them had gone in in just the last four days.
The planes on Tuesday will be carrying medical aid urgently needed in Gaza as well as food, particularly for children, and winter clothing as the rainy season begins, according to officials.
The aid will be delivered by the United Nations to civilians.
Two more planeloads are expected to follow in the coming days, officials said. Previously, there were also five commercial flights of aid coordinated by the U.S. government, according to officials.
The officials emphasized this aid as part of U.S. President Joe Biden’s commitment to helping the Palestinian people, saying that he has made sure America is the largest single donor both to the United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) and to Palestinian territories.
Going forward, the officials said the goals for humanitarian aid in Gaza will be expanding access, pushing for restoration of essential services, especially water, and keeping civilians out of harms way.
"The president has also consistently stressed the importance of ensuring military operations are conducted in a manner consistent with international humanitarian law, including with respect to the protection of civilians," the senior Biden administration official told reporters.
Officials did not offer any new information on the hostage negotiations between Gaza's militant rulers, Hamas, and Israel but reiterated that they hope to see Americans released in the coming days.
