Netanyahu says Israeli strikes across Gaza that killed hundreds are 'only the beginning'

DEIR AL-BALAH, Gaza Strip (AP) — Israel launched airstrikes across the Gaza Strip early Tuesday that killed more than 400 Palestinians, local health officials said, shattering a ceasefire in place since January as it vowed to force Hamas to release more hostages and relinquish control of the territory.

Prime Minister Benjamin Netanyahu ordered the strikes after Hamas refused Israeli demands to free half of the remaining hostages as a precondition for extending the ceasefire. Israel’s deadliest bombardment of the territory in the 17-month war killed mostly women and children, according to the Gaza Health Ministry.

Netanyahu said the attack was “only the beginning” and that Israel would press ahead until it achieves all of its war aims — destroying Hamas and freeing all hostages held by the militant group.

Hamas said at least six senior officials were killed in Tuesday’s strikes. Israel said they included the head of Hamas’ civilian government, a justice ministry official and two security agency chiefs.

All further ceasefire negotiations will take place “under fire,” he said in a statement aired on national television. The White House said it had been consulted and voiced support for Israel’s actions.

The Israeli military ordered people to evacuate eastern Gaza and head toward the center of the territory, indicating that Israel could soon launch renewed ground operations. The new campaign comes as aid groups warn supplies are running out two weeks after Israel cut off all food, medicine, fuel and other goods to Gaza’s 2 million Palestinians.

The pre-dawn barrage across Gaza struck homes and shelters and set a tent camp ablaze as families slept or prepared the “sohour,” the meal Muslims eat before they start the daily fast in the holy month of Ramadan. In Gaza City, Omar Greygaa said that after the strikes, he ran out to help survivors in a nearby stricken building.

“In every room I found the dead. ... I finish in one place and go to another, and I find more dead,” he said. “I don't know if we're in a state of war or truce.”

The attack could signal the full resumption of a war that has already killed tens of thousands of Palestinians and caused widespread destruction across Gaza. It also raised concerns about the fate of the roughly two dozen hostages held by Hamas who are believed to still be alive.

A senior Hamas official said Netanyahu’s decision to return to war amounts to a “death sentence” for the remaining hostages. Izzat al-Risheq accused Netanyahu of launching the strikes to save his far-right governing coalition.

There were no reports of any attacks by Hamas several hours after the bombardment.

But Yemen’s Houthi rebels fired rockets toward Israel for the first time since the ceasefire began. The volley set off sirens in Israel’s southern Negev desert but was intercepted before it reached the country’s territory, the military said. The U.S. over the weekend launched deadly strikes against the Iranian-backed Houthis.

Israel’s return to a military campaign came as Netanyahu faces mounting domestic pressure, with mass protests planned over his handling of the hostage crisis and his decision to fire the head of Israel’s internal security agency. His latest testimony in a long-running corruption trial was canceled after the strikes.

The strikes appeared to give Netanyahu a political boost. A far-right party led by Itamar Ben-Gvir that had bolted the government over the ceasefire announced Tuesday it was rejoining.

The main group representing families of the hostages accused the government of “deliberately dismantling” the ceasefire. Thousands of Israelis packed a Tel Aviv square Tuesday evening to protest Netanyahu’s intention to fire the country’s domestic security chief and demand the government to resume negotiations for a hostage deal.

“Today Netanyahu did not open the gates of hell on Hamas. He opened the gates of hell on our loved ones,” said Einav Zangauker, whose son is among the hostages.

After two months of relative calm during the ceasefire, stunned Palestinians found themselves once again digging loved ones out of rubble and holding funeral prayers over the dead at hospital morgues.

“Nobody wants to fight,” Nidal Alzaanin, a resident of Gaza City, said. “Everyone is still suffering from the previous months.”

A hit on a home in Rafah killed 17 members of one family, according to the European Hospital, which received the bodies. The dead included five children, their parents, and another father and his three children. Another in Gaza City killed 27 members of a family, half of them women and children, including a 1-year-old, according to a list of the dead put out by Palestinian medics.

By noon on Tuesday, Nasser Hospital had received the bodies of at least 28 children killed in recent violence, according to records shared by Ahmed Al-Farra, head of pediatrics and obstetrics.

At Khan Younis’s Nasser Hospital, patients lay on the floor, some screaming. A young girl cried as her bloody arm was bandaged. Wounded children overwhelmed the pediatric ward, said Dr Tanya Haj-Hassan, a volunteer with Medical Aid for Palestinians aid group.

She said she helped treat a 6-year-old girl with internal bleeding. When they pulled away her curly hair, they realized shrapnel had also penetrated the left side of her brain, leaving her paralyzed on the right side. She was brought in with no ID, and “we don’t know if her family survived,” Haj-Hassan said.

Gaza’s Health Ministry said the strikes killed at least 404 people and wounded more than 560. Zaher al-Waheidi, head of the ministry’s records department, said at least 263 of those killed were women or children under 18. He described it as the deadliest day in Gaza since the start of the war.

In his statement Tuesday, Netanyahu blamed Hamas for civilian casualties, saying it operates among the population.

The war has killed over 48,500 Palestinians, according to local health officials, and displaced 90% of Gaza’s population. The Health Ministry doesn’t differentiate between civilians and militants but says over half of the dead have been women and children.

The war erupted when Hamas-led militants stormed into southern Israel on Oct 7, 2023, killing some 1,200 people, mostly civilians, and taking 251 hostages. Most have been released in ceasefires or other deals, with Israeli forces rescuing only eight and recovering dozens of bodies.

The White House blamed Hamas for the renewed fighting. National Security Council spokesman Brian Hughes said the militant group “could have released hostages to extend the ceasefire but instead chose refusal and war.”

The ceasefire deal that the U.S. helped broker, however, did not require Hamas to release more hostages to extend the halt in fighting beyond its first phase.

An Israeli official, speaking on condition of anonymity to discuss the unfolding operation, said Israel was striking Hamas’ military, leaders and infrastructure and planned to expand the operation beyond air attacks.

The official accused Hamas of attempting to rebuild and plan new attacks. Hamas militants and security forces quickly returned to the streets in recent weeks after the ceasefire went into effect. Hamas on Tuesday denied planning new attacks.

Under the ceasefire that began in mid-January, Hamas released 25 hostages and the bodies of eight more in exchange for more than 1,700 Palestinian prisoners as agreed in the first phase.

But Israel balked at entering negotiations over a second phase. Under the agreement, phase two was meant to bring the freeing of the remaining 24 living hostages, an end to the war and full Israeli withdrawal from Gaza. Israel says Hamas also holds the remains of 35 captives.

Instead, Israel demanded Hamas release half of the remaining hostages in return for a ceasefire extension and a vague promise to eventually negotiate a lasting truce. Hamas refused, demanding the two sides follow the original deal, which called for the halt in fighting to continue during negotiations over the second phase.

Israel says it will not end the war until it destroys Hamas’ governing and military capabilities and frees all hostages — two goals that could be incompatible.

A full resumption of the war would allow Netanyahu to avoid the tough trade-offs called for in the second phase and the thorny question of who would govern Gaza.

It would also shore up his coalition, which depends on far-right lawmakers who want to depopulate Gaza and rebuild Jewish settlements there.

NEW YORK (AP) — Thousands of nurses in three hospital systems in New York City went on strike Monday after negotiations through the weekend failed to yield breakthroughs in their contract disputes.

The strike was taking place at The Mount Sinai Hospital and two of its satellite campuses, with picket lines forming. The other affected hospitals are NewYork-Presbyterian and Montefiore Medical Center in the Bronx.

About 15,000 nurses are involved in the strike, according to New York State Nurses Association.

“After months of bargaining, management refused to make meaningful progress on core issues that nurses have been fighting for: safe staffing for patients, healthcare benefits for nurses, and workplace violence protections,” the union said in a statement issued Monday. “Management at the richest hospitals in New York City are threatening to discontinue or radically cut nurses’ health benefits.”

The strike, which comes during a severe flu season, could potentially force the hospitals to transfer patients, cancel procedures or divert ambulances. It could also put a strain on city hospitals not involved in the contract dispute, as patients avoid the medical centers hit by the strike.

The hospitals involved have been hiring temporary nurses to try and fill the labor gap during the walkout, and said in a statement during negotiations that they would “do whatever is necessary to minimize disruptions.” Montefiore posted a message assuring patients that appointments would be kept.

“NYSNA’s leaders continue to double down on their $3.6 billion in reckless demands, including nearly 40% wage increases, and their troubling proposals like demanding that a nurse not be terminated if found to be compromised by drugs or alcohol while on the job," Montefiore spokesperson Joe Solmonese said Monday after the strike had started. "We remain resolute in our commitment to providing safe and seamless care, regardless of how long the strike may last.”

New York-Presbyterian accused the union of staging a strike to “create disruption,” but said in a statement that it has taken steps to ensure patients receive the care they need.

"We’re ready to keep negotiating a fair and reasonable contract that reflects our respect for our nurses and the critical role they play, and also recognizes the challenging realities of today’s healthcare environment,” the statement said.

The work stoppage is occurring at multiple hospitals simultaneously, but each medical center is negotiating with the union independently. Several other hospitals across the city and in its suburbs reached deals in recent days to avert a possible strike.

The nurses’ demands vary by hospital, but the major issues include staffing levels and workplace safety. The union says hospitals have given nurses unmanageable workloads.

Nurses also want better security measures in the workplace, citing incidents like a an incident last week, when a man with a sharp object barricaded himself in a Brooklyn hospital room and was then killed by police.

The union also wants limitations on hospitals’ use of artificial intelligence.

The nonprofit hospitals involved in the negotiations say they’ve been working to improve staffing levels, but say the union’s demands overall are too costly.

Nurses voted to authorize the strike last month.

Both New York Gov. Kathy Hochul and Mayor Zohran Mamdani had expressed concern about the possibility of the strike. As the strike deadline neared, Mamdani urged both sides to keep negotiating and reach a deal that “both honors our nurses and keeps our hospitals open.”

“Our nurses kept this city alive through its hardest moments. Their value is not negotiable,” Mamdani said.

State Attorney General Letitia James voiced similar support, saying "nurses put their lives on the line every day to keep New Yorkers healthy. They should never be forced to choose between their own safety, their patients’ well-being, and a fair contract.”

The last major nursing strike in the city was only three years ago, in 2023. That work stoppage, at Mount Sinai and Montefiore, was short, lasting three days. It resulted in a deal raising pay 19% over three years at those hospitals.

It also led to promised staffing improvements, though the union and hospitals now disagree about how much progress has been made, or whether the hospitals are retreating from staffing guarantees.
