Israel live updates: At least 11 Americans killed, may be among those held by Hamas

(NEW YORK) — At least 900 people have died and more than 2,500 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 2 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 have died in Gaza since Saturday. Unlike Israel, the Gaza Strip has no air raid sirens or bomb shelters.

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 are among those killed in Israel, President Joe Biden said in a statement.

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.

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.”

Israel Defense Forces: ‘Unprecedented attack … will be followed by an unprecedented Israeli response’

Lt. Col. Jonathan Conricus, spokesperson for the Israel Defense Forces, called Hamas’ attack “unprecedented,” and said the assault will be “followed by an unprecedented Israeli response.”

“I could not imagine at that time [when the incursion began Saturday] that Hamas would have the audacity … to do what they have done,” he told ABC News Monday. “To launch such an unprecedented, brutal, merciless attack on Israeli citizens. … And cause the amount of casualties that Israel has never experienced ever in its history.”

In Israel, at least 700 people have died and more than 2,300 others have been injured since Saturday.

The Israel Defense Forces has since launched retaliatory airstrikes on Gaza. At least 560 people have died and another 2,900 have been injured in Gaza since Saturday, Palestinian authorities said.

‘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.”

“We emphatically stand in unflinching support of Palestine; however, we are not involved in Palestine’s response, as it is taken solely by Palestine itself.,” the Iranian Mission to the UN said in a statement late Sunday. “The resolute measures taken by Palestine constitute a wholly legitimate defense against seven decades of oppressive occupation and heinous crimes committed by the illegitimate Zionist regime.”

A U.S. official said Saturday it was “too early” to tell if Iran had involvement in the attacks.

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 Prime Minister Benjamin Netanyahu made a video statement on social media, saying simply, “We are at war. We will win,” in his first comments, made in Hebrew, after the attack.

“Citizens of Israel, we are at war, not in an operation or in rounds, but at war. This morning, Hamas launched a murderous surprise attack against the State of Israel and its citizens. We have been in this since the early morning hours. I convened the heads of the security establishment and ordered – first of all – to clear out the communities that have been infiltrated by terrorists,” Netanyahu said. “This currently is being carried out. At the same time, I have ordered an extensive mobilization of reserves and that we return fire of a magnitude that the enemy has not known. The enemy will pay an unprecedented price. In the meantime, I call on the citizens of Israel to strictly adhere to the directives of the IDF and Home Front Command. We are at war and we will win it.”
