Israeli troops and tanks launched an hourslong ground raid into northern Gaza overnight into Thursday, the military said, striking several terrorist targets in order to prepare the battlefield ahead of a widely expected ground invasion after more than two weeks of devastating air raids.

The raid came after the UN warned it is on the verge of running out of fuel in the Gaza Strip, forcing it to sharply curtail relief efforts in the territory, which has also been under a complete siege since Hamas bloody rampage across southern Israel ignited the war earlier this month.

The rising death tolls in Gaza are unprecedented in the decades-long Israeli-Palestinian conflict.

Even greater loss of life could come if Israel launches an expected ground offensive aimed at crushing Hamas, which has ruled Gaza since 2007 and survived four previous wars with Israel.

The Health Ministry in Hamas-ruled Gaza said Wednesday that more than 750 people were killed over the past 24 hours, higher than the 704 killed the previous day.

The Associated Press could not independently verify the death toll, and the ministry does not distinguish between civilians and combatants.

By comparison, 2,251 Palestinians, mostly civilians, were killed in the entire six-week-long war in 2014, according to UN figures.

In preparation for the next stages of combat, the IDF operated in northern Gaza.

On Wednesday, the wife, son, daughter and grandson of Wael Dahdouh, a veteran Al-Jazeera correspondent in Gaza, were killed in an Israeli strike.

The Qatar-based network showed footage of his grief upon entering a hospital and seeing his dead son. Dahdouh and other mourners attended the funerals on Thursday wearing the blue flak jackets used by reporters in the Palestinian territories.

The Israeli military says it only strikes terrorist targets and accuses Hamas of operating among civilians in densely-populated Gaza.

During the overnight raid, soldiers killed fighters and destroyed terrorists infrastructure and anti-tank missile launching positions, the military said.

It said no Israeli were wounded.

There was no immediate confirmation of any Palestinian casualties.

Rear Adm. Daniel Hagari, a military spokesman, said the limited incursion was part of our preparations for the next stages of the war.

Israel also said it had also carried out some 250 airstrikes across Gaza in the last 24 hours, targeting tunnel shafts, rocket launchers and other terrorist infrastructure. 7 A portion of a building is destroyed during Israel’s raid overnight on Thursday, Oct. 26, 2023.IDF/X

An airstrike on the southern town of Khan Younis hit a residential building where 75 people were staying, according to family members, including 25 who had fled other parts of Gaza.

Ambulances streamed into the nearby Nasser Hospital, but there was no official word on casualties.

The Gaza Health Ministry says more than 6,500 Palestinians have been killed in the war.

That figure includes the disputed toll from an explosion at a hospital last week.

The fighting has killed more than 1,400 people in Israel, mostly civilians slain during the initial Hamas attack, according to the Israeli government.

Hamas also holds at least 224 hostages in Gaza. 7 Smoke billows in the air over the northern Gaza Strip on the morning of Thursday, Oct. 26, after a “column of tanks and infantry” launched an overnight raid into Hamas-controlled Gaza.AFP via Getty Images

The warning by the UN agency for Palestinian refugees, UNRWA, over depleting fuel supplies raised alarm that the humanitarian crisis could quickly worsen.

Gazas population has also been running out of food, water and medicine.

About 1.4 million of Gazas 2.3 million residents have fled their homes, with nearly half of them crowded into UN shelters.

Hundreds of thousands remain in northern Gaza, despite Israel ordering them to evacuate to the south, saying those who remain might be considered accomplices of Hamas. 7 People search for survivors and the bodies of victims through the rubble of buildings destroyed by Israeli forces in the southern Gaza strip on Oct. 26, 2023.

In recent days, Israel let more than 60 trucks with aid enter from Egypt, which aid workers say is insufficient and only a tiny fraction of what was being brought in before the war.

Israel is still barring deliveries of fuel needed to power generators saying it believes Hamas will take it.

An official with the International Committee of the Red Cross said it hopes to bring in eight trucks filled with vital medical supplies.

This is a small amount of what is required, a drop in the ocean, said William Schomburg, head of the sub-delegation in Gaza. We are trying to establish a pipeline.

UNRWA has been sharing its own fuel supplies so that trucks can distribute aid, bakeries can feed people in shelters, water can be desalinated, and hospitals can keep incubators, life support machines and other vital equipment working. 7 Smoke rises from the an Israeli attack in Khan Yunis on Thursday, Oct. 26.AFP via Getty Images

If it continues doing all of that, fuel will run out by Thursday, so the agency is deciding how to ration its supply, UNRWA spokeswoman Tamara Alrifai told The Associated Press.

Do we give for the incubators or the bakeries? she said. It is an excruciating decision.

More than half of Gazas primary health care facilities and roughly a third of its hospitals have stopped functioning, the World Health Organization said.

At Gaza Citys al-Shifa Hospital, the lack of medicine and clean water have led to alarming infection rates, the group Doctors Without Borders said.

Amputations are often required to prevent infection from spreading in the wounded, it said. see also Israel war 2023 Israel agrees to delay Gaza offensive to allow US missile defense placement

One surgeon with the group described amputating half the foot of a 9-year-old boy with only slight sedation on a hallway floor as his mother and sister watched.

The conflict has also threatened to spread across the region.

The Israeli military said Wednesday it struck military sites in Syria in response to rocket launches from the country.

Syrian state media said eight soldiers were killed and seven wounded.

Strikes in Syria also hit the airports of Aleppo and Damascus, in an apparent attempt to prevent arms shipments from Iran to terrorist groups, including Lebanons Hezbollah.

Israel has been exchanging near daily fire with Iranian-backed Hezbollah across the Lebanese border.

Israeli airstrikes and drone attacks early Thursday caused fires in open land in the southern Lebanon border town of Aita al Shaab, where clashes have intensified, Lebanons state-run news agency said.

It reported strikes late Wednesday on towns in the Tyre district, saying a mattress factory was hit. 7 A tank fires a round after crossing the border into the Gaza Strip during an overnight raid by Israeli forces.IDF/X

Hamas surprise rampage on Oct. 7 in southern Israel stunned the country with its brutality, its unprecedented toll and the failure of intelligence agencies to know it was coming.

Prime Minister Benjamin Netanyahu said in a peech Wednesday night that he will be held accountable, but only after Hamas was defeated.

We will get to the bottom of what happened, he said. This debacle will be investigated. Everyone will have to give answers, including me.
