More than a month after Hamas terrorists launched an unprecedented surprise attack on Israel and infiltrated the country by air, land and sea on Oct. 7, the region stands on high alert amid fears of a wider conflict and thousands dead on both sides of the Israel-Gaza border.
According to the Israeli prime minister's office, more than 1,200 people have been killed in Israel, with 6,900 others injured. Israeli officials say 383 Israel Defense Forces soldiers have been killed since Oct. 7, including 68 since the ground campaign began.
On Nov. 22, Israel's Cabinet approved a deal that would allow for the release of at least 50 hostages -- women and children -- over the course of a four-day pause in fighting, Prime Minister Benjamin Netanyahu said. As a part of this deal, 150 Palestinian prisoners will also be released by Israel. Netanyahu said in a release the "Israeli government has approved the outline to the first phase" of bringing hostages home.
Three Americans -- including a 3-year-old -- are expected to be part of the initial group of hostages that will be released, according to a senior administration official. The deal was negotiated between Hamas, Israel, Qatar and the United States. White House national security adviser Jake Sullivan said Nov. 12 at least nine Americans remain unaccounted for. Israeli officials have said Hamas is believed to be holding 236 hostages in Gaza.
The Hamas-run Gaza Health Ministry says at least 14,532 people have been killed in Gaza amid Israel's retaliatory campaign and ground operations began. More than 35,000 have been injured, the ministry says, with almost 1.5 million people displaced, according to the United Nations Relief and Works Agency. As of Nov. 3, 67% of all deaths in Gaza were made up of women and children while thousands more have been injured, according to several U.N. agencies, including the UNRWA. In the West Bank, about 215 people have been killed and more than 2,500 injured, according to the Palestinian Ministry of Health.
Israeli and U.S. officials have said the Hamas-run Gaza Health Ministry inflates the number of civilian casualties, with Netanyahu having said thousands of the dead are Hamas terrorists.
The conflict was touched off a month ago by the sneak attack, which included thousands of armed Hamas terrorists breaching a border security fence separating Gaza from Israel, and indiscriminately torturing and gunning down Israeli civilians in their homes, also attacking soldiers, caught off guard, on military bases. Other militants stormed beaches in Israel on motorboats. And some brought death from the sky, paragliding into Israel, to launch a barbaric attack at an open-air music festival that had been billed as a celebration of "unity and love."
In the immediate aftermath of the Oct. 7 Hamas attack, which also included thousands of missiles launched at Israel from the Gaza Strip, the IDF began its campaign of retaliation, bombarding Gaza with airstrikes. Israel soon vowed to eradicate Hamas, the terrorist organization that runs Gaza and is believed to operate with the backing of Iran.
Here are the key developments that have happened so far in the war:

Israeli officials announce that fighting is ongoing in six places, including Sderot -- which sits just 2 miles from the border with Gaza -- and that a rocket injured four people.
Videos posted online show a packed all-night music festival in a desert in southern Israel near the Gaza border being attacked by rockets and armed Hamas militants on the ground. The footage shows women and children among those being dragged away in vehicles and driven back into Gaza. Israeli rescue service Zaka says at least 260 bodies were removed from the venue following the attack.
Secretary of State Antony Blinken tells ABC's "This Week" anchor George Stephanopoulos that the U.S. has pledged its full support to Israel and says, "The world should be revolted at what it's seen."
Air sirens sound in northern Israel, prompting residents to rush to safe rooms. The IDF claimed at least two rockets were fired toward northern Israel from Lebanon. One of the rockets, according to the IDF, landed in Lebanese territory.

Hamas says it will start killing Israeli hostages one by one, threatening to film the executions, unless Israel immediately stops shelling homes in Gaza without warning.
The U.S. confirms that an undetermined number of Americans had been taken hostage by Hamas.
"I've directed my team to share intelligence and deploy additional experts from across the United States government to consult with and advise Israeli counterparts on hostage recovery efforts. Because as president, I have no higher priority than the safety of Americans being held hostage around the world," Biden says.
Biden says the atrocities committed by Hamas fighters included the "slaughter" of men, women and entire families, as well as "stomach-churning reports of babies being killed."
Gallant tours southern Israel along the Gaza border, telling soldiers they are moving to "a full-scale response" to Hamas' surprise attack and that he has "removed every restriction."
"Hamas wanted to see a change in Gaza -- the reality is Gaza will make a 180. They will regret [their actions]," Gallant said.
The IDF calls for "all residents of Gaza City to evacuate their homes" and "move south for their protection."
Israel begins warning more than 1 million Palestinians to move to a safer part of the territory, in southern Gaza, as Israeli soldiers prepared what was expected to be a massive ground campaign against Hamas fighters, many of whom are believed to be hiding in a miles-long network of tunnels under residential neighborhoods.
Israeli Minister of Defense Gallant has said the Israeli military is doing everything possible to prevent civilian loss of life.

The IDF announces it is preparing to implement an "integrated and coordinated attack from the air, sea and land" with an emphasis on a "significant ground operation."
Sari Bashi, program director for Human Rights Watch, tells ABC News Live that the situation in Gaza is "about as bad as it can get."
"People are being forced to drink brackish, untreated water because the price of bottled water has gone up beyond what most people can afford," Bashi says. "Food is short, there is no electricity. Even emergency generators that hospitals have are running low on fuel, and supplies are dwindling."
The number of U.S. citizens determined to have been killed in the Hamas attack on Israel rises to 31. At least 13 American nationals are still missing, a State Department spokesperson says.

The Hamas-run Gaza Health Ministry says hundreds of people are killed in an explosion outside the al-Ahli Hospital in the middle of Gaza City, which was being used to shelter thousands of displaced residents.
Palestinian officials claim an Israeli airstrike hit the hospital. The IDF denies responsibility for the blast, saying a failed rocket launched by the Palestinian Islamic Jihad caused it. Netanyahu says, "The barbaric terrorists in Gaza are the ones who attacked the hospital." A senior U.S. official tells ABC News at the time that U.S. officials at this point "just don't know where the rocket came from."
Days later, on Oct. 24, U.S. intelligence officials confirmed a preliminary U.S. government assessment "with high confidence that Israel was not responsible for the explosion of the hospital and that Palestinian militants were responsible." The assessment added "with low confidence" that Islamic Jihad "was responsible for launching the rocket that landed on the hospital." Some news outlets reported that a U.S. intelligence assessment estimated between 100 and 300 people were likely killed in the blast.
The incident led to anti-Israel and anti-American protests in the Arab world.
Under the threat of rocket strikes and heightened security, President Biden arrives in Israel Wednesday morning and is greeted with an embrace by Prime Minister Netanyahu on the tarmac of Ben Gurion Airport near Tel Aviv.
During a joint appearance with Netanyahu, Biden says he is "proud to be here."
"I want to say to the people of Israel, their courage, their commitment, their bravery is stunning, it's really stunning," Biden says, vowing to supply Israel with whatever it needs to defend itself.
In response, Netanyahu says, "Thank you, Mr. President. Thank you for standing with Israel today, tomorrow and always."

President Biden returns to the White House from Israel and plans to address the nation Thursday night, laying out the United States' response to the Hamas attacks on Israel. During his flight back to Washington on Air Force One, Biden tells reporters he had "blunt" talks with Israeli and Egyptian leaders about providing humanitarian aid to civilians trapped in Gaza, saying he negotiated an agreement to open the Rafah crossing gate in southern Gaza to allow up to 20 trucks with aid through.
"I came to get something done -- I got it done," he says, adding that the aid could start rolling into Gaza as early as Friday.
In his prime-time address Thursday evening, Biden is expected to lay out the "moment that we are in" with wars raging in the Middle East and Ukraine, how they connect to the lives of Americans at home, and how the administration and Congress need to respond so that resources from the United States continue to support both Israel and Ukraine, deputy national security adviser John Finer says on ABC's "Good Morning America."
Meanwhile, the IDF says it has determined that the number of Israeli hostages taken by Hamas is up to 203.
Avi Dichter, a member of the Israeli security cabinet, tells ABC News that Hamas and the Islamic Jihad in Gaza have a combined 50,000 fighters and that the Israeli military, which has mobilized more than 400,000 soldiers, has the "green light" to move into Gaza and begin its mission of "destroying Hamas."
Americans Judith Raanan, 59, and her daughter, Natalie Raanan, 17, were released by Hamas to the Red Cross and are now back in Israel, Israel Defense Forces says.
The death toll in Gaza has exceeded 5,000 so far in the war, which is now on its 16th day, according to the Palestinian Health Authority.
Meanwhile, two hostages have been released by Hamas, the Israeli Hostage Center confirmed. The hostages are two elderly women who are both Israeli nationals, the center said. The released hostages are 85-year-old Yocheved Lifshitz and 79-year-old Nurit Cooper, both from the Kibbutz Nir Oz, the center said.
The Red Cross said it helped transport the hostages out of Gaza Monday evening. The hostages have since arrived back in Israel, the hostage center said. The Israeli military said Monday that at least 222 hostages were taken by Hamas since Oct. 7. Two American hostages, a mother and daughter, have also been released.
The Family Forum of the Missing and Hostages said in a statement, "Over 200 Israeli citizens are being held in deplorable conditions and have been waiting to return home for 17 days. We call on the Israeli government and world leaders to bring everyone home now."
Prime Minister Netanyahu announces that the war on Hamas had entered a "new phase," including increased aerial attacks and broader, sustained ground operations.

"This shows the full barbarity behind the Hamas attack -- who must be held accountable." Scholz says. "This is terror, and Israel has the right to defend itself."
Gaza's Jabalia refugee camp, the most populous refugee camp in the region, is hit by a second airstrike, according to the Hamas-run Gaza Health Ministry.
The Israel Defense Forces confirms that on Nov. 1, "based on precise intelligence, IDF fighter jets struck a Hamas command and control complex" in Jabalia, and that Hamas fighters were killed in the strike.
"Hamas deliberately builds its terror infrastructure under, around and within civilian buildings, intentionally endangering Gazan civilians," the IDF says. "The IDF has been urging Gazans in this neighborhood to evacuate as part of its efforts to mitigate harm to civilians. The IDF continues to call on all residents of northern Gaza and Gaza City to evacuate southwards to a safer area."
The IDF also takes responsibility for the first strike on Oct. 31, saying the blast killed a Hamas official who the IDF claimed was one of the leaders of the Oct. 7 attack on Israel.
The border crossing between Gaza and Egypt opens on Nov. 1, allowing some foreign nationals and injured Gaza residents to exit the enclave for the first time since the Israel-Hamas war began on Oct. 7.

The Rafah border crossing, which is controlled by Egypt, was expected to allow about 500 foreign passport holders to exit, according to the Gaza Borders and Crossings Authority, which released a list of names of those who would be allowed across. At least 110 dual nationals have crossed the Rafah border into Egypt, ABC News confirms.

Israeli Air Force planes continued their bombing campaign throughout Gaza, striking some 450 targets overnight, as other Israeli forces captured a Hamas compound, IDF officials said in a statement.
The Hamas compound included a web of "underground terror tunnels," as well as training areas and observation posts, the military said in a post on Telegram. Israel did not disclose the location of the compound. ABC News was not immediately able to verify the IDF's claims.
"During the operation, several Hamas terrorists were killed," Israel said.
At least 10,022 people have died in Gaza since the Israel-Hamas war began on Oct. 7, the Hamas-run Gaza Health Ministry said on Nov. 6.
As U.S. officials continued their calls for humanitarian "pauses" to allow aid to reach civilians stuck in Gaza, Israel showed no signs of slowing their advance.
Netanyahu, speaking with ABC News "World News Tonight" anchor David Muir in an exclusive interview, again rejected the idea of a cease-fire in Gaza unless hostages are released.
"What they're proposing is a humanitarian pause, there will be no pause?" Muir pressed Netanyahu, shortly after he had spoken with Biden.
"Well, there'll be no cease-fire, general cease-fire, in Gaza without the release of our hostages," Netanyahu responded. "As far as tactical little pauses, an hour here, an hour there. We've had them before, I suppose, will check the circumstances in order to enable goods, humanitarian goods to come in, or our hostages, individual hostages to leave. But I don't think there's going to be a general cease-fire."
Israel will start to implement four-hour pauses in fighting in areas of northern Gaza each day, National Security Council spokesperson John Kirby announces.
"We've been told by the Israelis that there will be no military operations in these areas over the duration of the pause, and that this process is starting today," Kirby says.
IDF spokesman Richard Hecht says the pauses are already being held. Kirby says the pauses will be announced three hours ahead of time.
Kirby says the Israelis have also agreed to a second humanitarian corridor that will allow people to leave hostile areas of northern Gaza.
The fighting around Al-Shifa Hospital in Gaza intensifies, and a strike hits the courtyard outside the hospital. The hospital loses power and ceases functioning as a hospital.

IDF intelligence shows that 19-year-old Noa Marciano, one of the hostages whose body was found near the Al-Shifa Hospital complex, was initially taken into Gaza alive after the Oct. 7 Hamas terrorist attack on Israel, the IDF says during a briefing.
After being taken into Gaza "during ongoing combat, in the vicinity of where she was held captive, Noa's Hamas captor was killed, and Noa was injured," IDF spokesman Daniel Hagari says.
"An independent pathological report has determined Noa's injuries were not life-threatening," he adds.
The IDF says that, "according to the intelligence we have in our hands ... Hamas terrorists took Noa into Shifa hospital where she was murdered quickly."
"We send our heartfelt condolences to Noa's family. We did not reach Noa in time. This has only made the IDF more determined to do everything, everything in our power, to bring all our hostages home," Hagari adds.

Netanyahu, speaking ahead of a Cabinet meeting and vote on a potential hostage deal, says Israel's war against Hamas will not stop after a cease-fire.
Netanyahu says the war will continue until Hamas is destroyed, all hostages are brought home, and Israel has ensured "that there will be no element in Gaza that threatens Israel."
Israel's Cabinet approved a deal that would allow for the release of at least 50 hostages over the course of a four-day pause in hostilities, Netanyahu announces. As a part of this deal, 150 Palestinian prisoners will also be released by Israel.
The "Israeli government has approved the outline to the first phase" of bringing hostages home, Netanyahu says in a release, with at least 50 being released over the course of the four-day pause in fighting.
