Secretary Of State Blinken Reaffirms U.S. Support For Israel As Conflict In Gaza Escalates

As Palestinians tried to stock up on bread and groceries amid dwindling supplies, Israel said nothing would be allowed into Gaza until around 150 hostages taken captive by Hamas during a weekend attack are freed.

International aid groups warned of worsening humanitarian crisis after Israel stopped all deliveries of food, water, fuel and electricity to the tiny enclave of 2.3 million people and prevented entry of supplies from Egypt. The war has already claimed at least 2,700 lives on both sides.

“Not a single electricity switch will be flipped on, not a single faucet will be turned on, and not a single fuel truck will enter until the Israeli hostages are returned home,” Israeli Energy Minister Israel Katz said on social media.

Lt. Col. Richard Hecht, an Israeli military spokesman, told reporters on Thursday that forces “are preparing for a ground maneuver” should political leaders order one. A ground offensive in Gaza, where the population is densely packed into a sliver of land only 40 kilometers (25 miles) long, would likely bring even higher casualties on both sides in brutal house-to-house fighting.

As Israel pounds Gaza from the air, Hamas militants have fired thousands of rockets into Israel.

Palestinians fleeing airstrikes in Gaza could be seen running through the streets, carrying their belongings and looking for a safe place. The number of people who fled their homes soared 30 per cent within 24 hours, reaching 340,000 people by Wednesday night. Most crowded into UN-run schools while others are staying with relatives or even strangers who let them in.

Lines formed outside bakeries and grocery stores during the few hours they dared open, as people tried to stock up before shelves emptied. On Wednesday, Gaza's only power station ran out of fuel and shut down, leaving only lights powered by scattered private generators.

Hospitals, overwhelmed by a constant stream of wounded and running out of supplies, have only a few days worth of fuel before their power cuts off, aid officials say. The cut-off has also caused dire water shortage for over 650,000 people, according to the UN.

“Without electricity, hospitals risk turning into morgues,” warned Fabrizio Carboni, regional director of the International Committee of the Red Cross. When power runs out, it puts "newborns in incubators and elderly patients on oxygen at risk. Kidney dialysis stops, and X-rays can't be taken", he said.

With Israel sealing off the territory, the only way in or out is through the crossing with Egypt at Rafah. Egypt's Foreign Ministry said it has not officially closed Rafah but airstrikes have prevented it from operating. Egypt has been trying to convince Israel and the United States to allow the delivery of aid and fuel through Rafah.

Israeli Prime Minister Benjamin Netanyahu vowed to “crush” Hamas after the militants stormed into the country's south on Saturday and massacred hundreds of people, including killings of children in their homes and young people at a music festival. Netanyahu alleged Hamas atrocities, including beheading soldiers and raping women. His allegations could not be independently confirmed.

Amid grief and demands for vengeance among the Israeli public, the government is under intense pressure to topple Hamas rather than continuing to try to bottle it up in Gaza.

Four previous conflicts ended with the group still firmly in control of the territory it has ruled since 2007. Israel has mobilised 360,000 reservists, massed additional forces near Gaza and evacuated tens of thousands of residents from nearby communities.

A new war Cabinet, which includes a longtime opposition politician, is now directing the fight.

Blinken's visit underscored American backing for Israel's retaliation.

“You may be strong enough on your own to defend yourselves, but as long as America exists you will never have to,” Blinken said after meeting with Netanyahu in Tel Aviv. “We will always be there by your side.”

Blinken is to meet Friday with Palestinian President Mahmoud Abbas, whose authority is confined to parts of the occupied West Bank, and Jordan's King Abdullah II.

Israel captured the West Bank, along with Gaza and east Jerusalem, in a 1967 war. The Palestinians want all three territories for their future state, but there have been no peace talks in over a decade.

In Gaza, the Israeli military said overnight strikes targeted Hamas' elite Nukhba forces, including command centres used by the fighters who attacked Israel on Saturday, and the home of a senior Hamas naval operative that it said was used to store unspecified weapons. Other airstrikes killed commanders from two smaller militant groups, according to media linked to those organisations.

“Right now we are focused on taking out their senior leadership,” Hecht, the military spokesman, said of Hamas. “Not only the military leadership, but also the governmental leadership, all the way up to (top Hamas leader Yehia) Sinwar.”

Drone footage filmed by The Associated Press revealed extensive damage at the Shati refugee camp, in the north of Gaza, following overnight airstrikes. Residents picked their way through the rubble as fire and rescue crews looked for survivors.

While Israel has insisted that it is giving notice of its strikes, it is employing a new tactic of levelling whole neighbourhoods, rather than just individual buildings.

Hecht said Israel was not “doing carpet bombing, though some people would like to see that.” He said targeting decisions were based on intelligence and civilians were warned.

Even with the warnings, Palestinians say some are unable to escape or have nowhere to go, and that entire families have been crushed under rubble. In the Gaza town of Beit Lahia, Israeli planes dropped leaflets telling people to leave after strikes had heavily blasted the area, residents said.

Jaber Weshah, a 73-year-old rights activist, said there was no warning when a strike levelled a multi-story building neighbouring his in the Bureij refugee camp early Wednesday. At least 12 people were killed, including a bookseller, his wife and two toddler daughters and six members of another family, residents said.

“It was an inferno,” Weshah said.

At least 1,000 homes have been levelled and 560 rendered uninhabitable by strikes, according to the UN.

The Palestinian Health Ministry said two Palestinians were killed in the West Bank on Thursday when Israeli settlers sprayed bullets at a funeral for three people killed in a settler rampage the day before. Footage showed Jewish settlers in their cars swerving into the funeral procession and cutting off the road before stopping and opening fire.

The Health Ministry says more than two dozen Palestinians have been killed in the West Bank and two in Israeli-annexed east Jerusalem since Saturday, most when police fired on stone-throwing protesters.

The death toll in Gaza rose to more than 1,400 killed, the Palestinian health ministry said.

The Israeli military said more than 1,300 people, including 222 soldiers, have been killed in Israel, a staggering toll unseen since the 1973 war with Egypt and Syria that lasted weeks.

Thousands have been wounded on both sides.

Israel says roughly 1,500 Hamas militants were killed inside Israel, and that hundreds of the dead inside Gaza are Hamas members.
