(NEW YORK) — At least 900 people have died and 2,600 others have been injured in Israel after the militant group Hamas launched an unprecedented incursion from air, land and sea on Saturday, Israeli authorities said.

Hamas fired thousands of rockets toward Israel and an estimated 1,000 fighters crossed into the country from the neighboring Gaza Strip. Israeli officials said at least 100 civilians and soldiers have been taken hostage.

The Israel Defense Forces has since declared “a state of alert for war” and launched retaliatory airstrikes on Gaza, a 140-square-mile territory where two million Palestinians have lived under a blockade imposed by neighboring Israel and Egypt since Hamas seized power in 2007. Palestinian authorities said at least 687 people, including 140 children, have died and 3,726 others have been injured in Gaza since Saturday. Unlike Israel, the Gaza Strip has no air raid sirens or bomb shelters.

Americans ‘could be among those being held hostage by Hamas,’ Kirby says

The United States is still working to determine how many Americans remain unaccounted for after Saturday’s attack on Israel by Hamas and whether any are among those being held hostage in the neighboring Gaza Strip, according to National Security Council spokesman John Kirby.

In an interview Tuesday with ABC News’ George Stephanopoulos on Good Morning America, Kirby said the number of unaccounted Americans in Israel “keeps changing” as families contact the U.S. Department of State.

“We’re trying to get a handle on where they are and how they are,” he added. “Sadly, we have to accept the possibility — the grim possibility — that some of those unaccounted for Americans could be among those being held hostage by Hamas.”

So far, U.S. officials have confirmed that at least 11 Americans were among those killed in Israel over the weekend when Hamas fighters stormed into the country from Gaza. U.S. officials are “preparing for the very distinct possibility that there’ll be more American deaths,” Kirby said.

Meanwhile, there’s currently no specific information on whether any Americans were among those taken hostage, according to Kirby. Israeli authorities have estimated that Hamas is currently holding “between 100 to 150” hostages in Gaza, including Americans.

“We’re working at this really, really hard, talking to the Israelis every single day — almost every hour — to try to get more information about the Americans that are unaccounted for,” Kirby said, “but we just don’t know where they are.”

U.S. officials have reached out to their Israeli counterparts to offer assistance in the form of intelligence and hostage recovery expertise, according to Kirby.

“It remains to be seen if there’s Americans in that group, what more can be done,” he said. “If there’s Americans being held hostage, we’ll do everything possible to get them home to their families where they belong.”

When asked whether the U.S. would be prepared to pay ransom, Kirby said: “I don’t want to get too far ahead of where we are.”

“We don’t even know if there are Americans in this population of hostages,” he added.

Israeli airstrikes target Gaza-Egypt border crossing

An Israeli airstrike hit near the Rafah border crossing between Egypt and the Gaza Strip on Tuesday for the second time in two days, Palestinian authorities said.

“The occupation aircrafts re-bombed the gate of the Rafah crossing between the Palestinian and Egyptian sides after it was repaired yesterday, preventing the departure and arrival of passengers,” Iyad Al-Bozom, spokesman for the Palestinian Ministry of Interior, said in a statement.

Operations at the frontier were disrupted on Monday after an Israeli airstrike hit near the border on the Gaza side. Officials on the Egyptian side of the Rafah crossing on Tuesday asked crews on the Palestinian side to immediately evacuate the crossing following threats to hit it, according to Al-Bozom.

Iran denies involvement in Hamas attack on Israel

Iranian Supreme Leader Ayatollah Ali Khamenei said Tuesday that Tehran was not involved in Hamas’ recent incursion on Israel but hailed the attack.

“The Zionist regime’s own actions are to blame for this disaster,” he added.

Iran, which does not recognize Israel, has acknowledged giving financial and moral support to Hamas, the militant group that controls the Gaza Strip.

IDF says Hamas fighters ‘are still hiding’ in Israeli communities

Hamas fighters are believed to be “still hiding” in some communities in southern Israel even after the Israeli military took back control, according to Israel Defense Forces spokesman Maj. Doron Spielman.

“We are in control of the communities, but we actually assume that there are Hamas terrorists that are still hiding in these areas, including in the road where we are now,” Spielman told ABC News during an interview Monday in Sderot, Israel. “In all these communities, we’ve seen terrorist come out of hiding. Just yesterday, they took over an ambulance.”

“We’re still being very, very careful,” he added. “This is a war zone with active terrorists that are operating here.”

Sderot is a southwestern Israeli city located near the county’s border with the Hamas-ruled Gaza Strip. A police station there was stormed by Hamas fighters on Saturday as part of the militant group’s wider incursion, leaving at least six Israeli police officers dead. The IDF then bombed the police station with the Hamas fighters inside, demolishing it.

Hamas fighters and other Palestinian militants are “striking strategic locations” along the border fence, allowing them to drive through in pickup trucks, Spielman said. Civilians in some of the local communities have been ordered to evacuate, while others have left voluntarily, according to Spielman.

“We do have a lot of ground troops in this area. We have a lot of tanks. We have, in addition, artillery. And we’re prepared forever for anything,” he said. “And if it happens, the next stage, it’s going to happen here because this is the area that was the flashpoint and this is the area we’re going to be presenting ourselves and finishing this battle. We, of course, have no choice but to finish.”

When asked about the mounting casualties of Palestinian civilians in Gaza as a result of the IDF’s retaliatory airstrikes, Spielman said: “We always try to avoid civilian casualties. However, I would say that this is war and our first priority here is to destroy Hamas.”

IDF fighter jets strike over 200 ‘terror targets’ in Gaza overnight

The Israel Defense Forces said Tuesday morning that its fighter jets had struck more than 200 “terror targets” in the Gaza Strip overnight.

All targets were located in the Rimal neighborhood of Gaza City and the southern city of Khan Yunis, which the IDF said are both used as “terror hubs” for Gaza’s militant rulers Hamas and that “a large number of terror attacks against Israel are directed there.”

Among the targets struck were a Hamas weapons storage site and a Hamas operational command center, both located inside a mosque, according to the IDF.

IDF says it will fight war ‘as long as it takes’

The Israel Defense Forces will fight this war “as long as it takes,” spokesperson Lt. Col. Res. Jonathan Conricus told ABC News in an interview on Monday.

“The goal that we have been given so far by the Israeli government is to make sure that Hamas doesn’t have any military capabilities that they can use to threaten or murder Israeli citizens. That means to eradicate their ability to terrorize Israelis,” Conricus said.

“That’s what we’ve been tasked to do so far — that may change, expand, and include political things as well as in their ability to govern, but as of now, what we’re focusing on with the aerial strikes that are ongoing and the preparations of the other troops around the Gaza Strip is to strip Hamas of all of their military capabilities,” he added.

The IDF is looking at “difficult and hard passes ahead,” but Saturday’s attack by Hamas fighters was a “watershed moment” that has fundamentally changed how the IDF responds, according to Conricus.

“Bottom line, what was true and perhaps worked for years before, won’t cut the situation now and we are moving forward,” he said.

In addition, 300,000 IDF reservists who were called up are “now in southern Israel,” according to Conricus.

“We have mobilized our troops before — the second Lebanon war comes to mind,” he added. “But this is definitely very, very significant.”

The White House released a statement shortly after President Biden spoke with key allies about the latest developments in Israel.

The leaders expressed their “steadfast and united support to the State of Israel, and our unequivocal condemnation of Hamas and its appalling acts of terrorism.”

“We make clear that the terrorist actions of Hamas have no justification, no legitimacy, and must be universally condemned,” the statement read.

The leaders said they will support Israel’s right to defend itself.

“We further emphasize that this is not a moment for any party hostile to Israel to exploit these attacks to seek advantage,” they said.

At the same time, the leaders said they “recognize the legitimate aspirations of the Palestinian people, and support equal measures of justice and freedom for Israelis and Palestinians alike.”

Son ‘sad,’ ‘anxious’ as 74-year-old mother remains missing

A 74-year-old mother who is missing in Israel fought for peace her whole life, her son told ABC News Live on Monday.

Yonatan Zeigen said he last heard from his mother, Vivian Silver, at 11:07 a.m. on Saturday morning while she was hiding in a closet as Hamas fighters entered her house.

Zeigen added that he didn’t know if Israeli soldiers had been to her house yet and hadn’t heard “anything concrete” about the search yet.

Zeigen talked about his mother’s commitment to peace, since Silver moved to a kibbutz in Israel in the 1990s.

“She fought for equality,” he said. “She’s been involved with a lot of different organizations promoting peace and promoting solution for the conflict.”

“Up until recently, she would drive sick Palestinians from the Gaza border to Israeli hospitals through an organization called Road to Recovery,” Zeigen said.

“No, I’m primarily sad, and anxious,” Zeigen said when asked if he was angry about the situation. “War is blind. You can do what you do in your life…it doesn’t make you any less of a target in times of war.”

State Department confirms Americans are missing, unknown if any are hostages

The State Department confirmed Monday evening that there are still missing Americans in Israel but couldn’t immediately provide an exact number or estimate.

The department couldn’t say yet if any of the missing Americans were hostages.

White House spokesperson John Kirby echoed this sentiment to ABC News’ Linsey Davis.

“We don’t really know whether they’re just missing somewhere, or are lost, or whether they’re being held hostage. I think we have to accept the possibility that at least some of them are being held hostage by Hamas,” he said.

Of the Americans previously confirmed dead, a State Department official said they were all thought to be dual U.S.-Israeli citizens primarily residing in Israel.

Staffers at the U.S. Embassy in Israel are fully accounted for and are communicating with impacted Americans around the clock over the telephone and via the online form the department launched for U.S. nationals who believe their family members are among those missing, according to the agency.

The State Department is also urging Americans in the affected areas who are safe to contact their loved ones directly and/or update their status on social media.

At least 11 Americans killed, more may be among those held by Hamas

At least 11 Americans are among those killed in Israel, President Joe Biden said in a statement.

He added, “While we are still working to confirm, we believe it is likely that American citizens may be among those being held by Hamas.”

“American citizens still remain unaccounted for, and we are working with Israeli officials to obtain more information as to their whereabouts,” Biden said. “My heart goes out to every family impacted by the horrible events of the past few days. The pain these families have endured, the enormity of their loss, and the agony of those still awaiting information is unfathomable.”

“I have directed my team to work with their Israeli counterparts on every aspect of the hostage crisis, including sharing intelligence and deploying experts from across the United States government to consult with and advise Israeli counterparts on hostage recovery efforts,” Biden said.

Survivors recount ‘living hell’ at Israel music festival

A 30-year-old Israeli told reporters it was “living hell” when Hamas gunmen opened fire and rockets were unleashed on a music festival in southern Israel, killing hundreds.

“I’ve been in wars, in two wars in my life, and never seen anything like this. Bodies at all places,” the 30-year-old said. “They didn’t care if you are a man or a woman, if you are young or an old man.”

At least 260 bodies were removed from the music festival venue, according to an Israeli rescue service.

Another survivor, Elad Hakim, told Reuters in Hebrew that the festival was “the best party I’ve been to in my life” until it went “from paradise to hell in one second.”

“Girls started screaming,” Hakim said. “People didn’t understand where to go, what to do.”

“There were two men on motorcycles on the road … who started spraying us [with bullets] as we drove by,” Hakim said. “The vehicles that were behind [us] were left behind.”

‘No one else should get involved in this,’ top US official warns

The United States is warning against other countries from becoming involved in the Israel-Gaza conflict amid fears that it could spread into a wider war in the Middle East.

“This is not the moment for other parties who are hostile to Israel to seek advantage or to seek to exploit the attacks that have taken place,” Jon Finer, deputy national security adviser to U.S. President Joe Biden, Monday on Good Morning America.

“That is part of why the United States has moved the Carrier Strike Group to the eastern Mediterranean to send a strong and unmistakeable signal that no one else should get involved in this,” he added. “We’ll see how things unfold in the course of the coming days.”

Finer also emphasized that the U.S. believes “Israel has every right to defend itself full-stop.”

“Israel will ultimately make the decisions about how it chooses to go about and conduct that defense,” he said. “We are offering support in a number of ways.”

Finer noted that “more U.S. steps to show support and solidarity for Israel” can be expected.

“The U.S. is going to offer support at every level for Israel’s defense and we are working through details those details with our intelligence professionals, our military and our diplomats,” he added. “We are in daily — in fact, many times a day — contact with Israeli counterparts to see what they need and offer it.”

The U.S. “strongly suspect[s] that there will be American citizens among those killed” in the ongoing conflict, according to Finer.

“We are looking obviously very intensively into whether there were any Americans were among those who have been abducted and brought to Gaza. This is still ongoing,” he said. “There is still fighting inside Israel as we speak and there is a bit of fog of war in terms of the ability to gather specific information. And so, we will have much more to say about this at the right time.”

When asked for comment on a recent report by The Wall Street Journal that Iran was behind Hamas’ latest attack on Israel, Finer responded: “We have no direct information to confirm that report. We’ve obviously seen it, we’re looking into it, but we do not have the ability to corroborate it at this time.”

“What we can be quite clear about is that Iran is broadly complicit in these attacks for having supported Hamas going back decades — for having provided financial support, for having provided training, for having provided weapons to Hamas,” he added. “What we don’t have is direct information that shows Iranian involvement in ordering or planning the attacks that took place over the last couple days. It’s something that we’re going to keep looking at closely.”

An emergency meeting of the United Nations Security Council failed to condemn the Hamas attacks on Israel Sunday evening.

US has for decades had vast weapons stockpile in Israel

The White House has pledged assistance to Israel in responding to Hamas’ attack — and America has for decades maintained a vast pre-positioned military stockpile inside Israel.

First established in the wake of the Yom Kippur War of 1973, when it took time for the U.S. to send supplies to Israel, the munitions are available in case of emergencies.

It’s possible that Israel will ask the U.S. to tap into this stockpile, which contains weapons systems including tanks and ammunition stored in warehouses.

While not especially well known to the public, the supplies got some exposure earlier this year when the U.S. planned to use them in order to send artillery to Ukraine in responding to Russia’s invasion.

Israeli ambassador to US calls attacks ‘war crimes’

In a strongly worded statement, Israel’s ambassador to the U.S. labeled the Hamas attacks as “war crimes” and vowed that Israel will fight back.

“Those of our enemies who believe that Israel is weak because of its internal debate have totally miscalculated. When under attack, Israelis close ranks and join together in fighting for Israel’s self-defense,” Michael Herzog declared. “This is war. We will fight to win and deter the terrorists from any future attacks.”

The ambassador also directly blamed Iran for the surprise attack, saying, “Hamas is a U.S. and E.U. designated terror organization and a close ally of Iran. Iran’s hands are evidently behind the scenes, leading the so-called Axis of Resistance to Israel’s existence.”
