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.
84-year-old Israeli hostage who was freed remains in critical condition
Alma Avraham, an 84-year-old Israeli hostage freed by Hamas on Sunday, remains hospitalized in critical condition, Israeli officials said Monday.
She suffers from preexisting conditions and was receiving regular medication before she was kidnapped, said Dr. Tzachi Slotsky, deputy administrator of Soroka Medical Center.
"If she hadn’t been transferred to us yesterday, or any other delay in her transfer, it would’ve worsened her condition even more," Slotsky said. "She is intubated and sedated at the emergency room and her life is still in danger."
Without care, she soon would have died, said Avraham's daughter, Tali Amano.
"My mother did not deserve to return this way -- my mother was medically neglected," Amano said. "She didn’t get any of her medication."
"The only reason we are standing here today ... is to save those who are left there [in Gaza]," Amano said.

1st photo released of 4-year-old hostage Abigail Idan after her return home
The family of 4-year-old hostage Abigail Idan has released the first photo of the little girl following her return home from Gaza.
Abigail, an American-Israeli citizen, had been held hostage by Hamas since Oct. 7. She was released on Sunday, two days after her 4th birthday.
Abigail Idan’s aunt, Ella Mor, said in a video Sunday, "She just landed in the hospital and she’s being checked and taken care of."
"I'm so happy that she's here," Mor told ABC News. "The people of Israel are amazing … everybody's so happy like she's their own little girl."
Problem with Monday's hostage list is it includes children without mothers, Israeli source says
Israel has taken issue with the list of hostages that Hamas said it would release on Monday because it includes children without their mothers, an Israeli source told ABC News.
However, the source said there is optimism that the issue will be resolved by Monday night and an extension to the four-day truce, set to expire Tuesday morning, will be approved.
The Israeli Prime Minister's Office confirmed in a statement that negotiations with Hamas on Monday's hostage list "are continuing."

Egypt says Israel, Hamas are close to reaching deal on truce extension
Egypt's State Information Service (SIS) announced Monday that Egyptian-Qatari mediation between Israel and Hamas is close to reaching an agreement to extend a four-day truce by two days.
The deal would also involve the release of 10 Israeli women and children being held hostage by Hamas in the Gaza Strip in exchange for 30 Palestinians detained in Israeli prisons each day of the extension, totaling 20 Israeli hostages and 60 Palestinian prisoners, according to SIS chairman Diaa Rashwan.
A cease-fire, the halt of air raids as well as the entry of aid and fuel into war-torn Gaza would continue during the additional two days of the truce, Rashwan said.
Rashwan also said that the fourth group of releases Monday would include 11 Israelis and 33 Palestinians.

French warship to serve as hospital for wounded Palestinians off coast of Egypt, source says
A French warship has arrived in Egypt's norther port city of El-Arish, near the border with the war-torn Gaza Strip, to serve as a hospital for wounded Palestinians, a diplomatic source told ABC News on Tuesday.
The Dixmude, the first Western military ship to dock in Egypt, has around 40 hospital beds and two surgical operation rooms. The vessel is expected to remain in El-Arish for about a month, the source said.
The ship carries military medics as well around two dozen civilian pediatricians and surgeons. Patients with permits are expected to leave Gaza for Egypt through the Egyptian-controlled Rafah border crossing, before being transported to the Dixmude for medical treatment, according to the source.
From there, patients should be transferred to Egyptian hospitals for later stages of treatment, the source said, but French officials have not yet reached an agreement with Egyptian authorities on that.
