Rafah, Palestinian Territories – AFP

Scores of Palestinians were killed in central Gaza on Sunday as Israel stepped up its strikes on the war-torn enclave and another convoy of 17 aid trucks arrived as the Hamas-run territory faces “catastrophic” shortages.

With Israel’s bombing remaining unchecked, Iran said the region could spiral “out of control”.

Israeli Prime Minister Benjamin Netanyahu issued a stark warning to Lebanon’s Hezbollah, saying getting involved would be “the mistake of its life”.

But Washington also fired a shot across the bows of any actors looking to inflame the conflict, saying it wouldn’t hesitate to act in the event of any “escalation”.

Hamas fighters stormed across the border into Israel on October 7, launching a raid that killed at least 1,400 people, according to Israeli officials. They also took more than 200 people prisoners.

Israel has hit back with a relentless bombing campaign which has so far killed more than 4,600 Palestinians, according to Gaza’s health ministry, with officials saying the central town of Deir al-Balah had been particularly badly hit overnight.

The ministry said at least 80 people had been killed in the overnight raids on central Gaza which had destroyed more than 30 homes.

At the hospital morgue, an AFP journalist saw the bodies of many children on the bloodied floor, where distraught families wept as they identified the victims.

Among them was a man clutching his dead toddler and a young boy who pulled back a blanket over his little sister’s body.

“My cousin was sleeping in his house with his daughter in his arms. He was a man with no record, nothing to do with the resistance,” said Wael Wafi, gazing at the body of his cousin, his arm still wrapped around his three-year-old daughter Misk.

Also Sunday, the UN agency for Palestinian refugees (UNRWA) said that 29 of its staff had been killed since the start of the war in a statement on X, formerly Twitter, saying half of them were teachers. On Saturday it had given a toll of 17.

The scale of the bombing has left basic systems unable to function, with the UN saying dozens of unidentified bodies had been buried in a mass grave in Gaza City because cold storage had run out.

Meanwhile, an Israeli soldier was killed near the Gaza border by an anti-tank missile fired from inside Gaza, the army said.

It said rocket warning sirens had sounded repeatedly in southern and central Israel throughout the day, including in the southern city of Beersheba.

– ‘Accident’ as Israel hits Egypt post –

Meanwhile, a second convoy of 17 trucks of aid entered Gaza from Egypt on Sunday following an initial delivery of 20 trucks on Saturday.

Separately, an AFP journalist saw six trucks leaving Rafah after filling up from dwindling fuel stocks held at the crossing as the enclave faces catastrophic shortages after Israel cut off supplies of food, water, fuel and electricity, although it later resumed water supplies to the south on October 15.

Egyptian media said another 40 trucks would enter Gaza on Monday, but the UN says the enclave needs 100 trucks per day to meet the needs of Gaza’s 2.4 million residents.

And so far, there have been no deliveries of fuel, with UNRWA chief Philippe Lazzarini warning Sunday that supplies would run out “in three days”.

“Without fuel, there will be no water, no functioning hospitals and.. aid will not reach many civilians in desperate need,” he said.

Israel on Sunday said it had accidentally hit an Egyptian border post with a tank shell and apologised for the incident which Cairo said had left an unspecified number of border guards with “minor injuries”.

The Egyptian army said they had been hit by “fragments of a shell accidentally fired from an Israeli tank” and that it was looking into the incident.

– Risk of regional escalation –

Meanwhile, there were fresh exchanges of fire over Israel’s northern border with Lebanon as fears grew that Hezbollah, a close ally of Hamas and Iran, could enter the conflict, prompting Netanyahu to warn it would be “the mistake of its life”.

“We will strike it with a force it cannot even imagine, and the significance for it and the state of Lebanon will be devastating,” he said.

Iran also warned about the conflict spreading on Sunday, with top diplomat Hossein Amir-Abdollahian cautioning that if Washington and Israel did not “immediately stop the crime against humanity and genocide in Gaza, anything is possible at any moment and the region will go out of control”.

But Washington said it wouldn’t hesitate to act in the event of any “escalation” in connection with Israel’s war against Hamas, just hours after the Pentagon moved to step up military readiness in the region.

“If any group or any country is looking to widen this conflict and take advantage of this very unfortunate situation that we see, our advice is: don’t,” US Defence Secretary Lloyd Austin said on ABC News.

With tensions rising, Israel has evacuated dozens of northern communities, and nearly 4,000 people have fled villages in south Lebanon for shelter in the southern city of Tyre.

Thousands rallied in Paris to demand an end to Israel’s operation in Gaza in the first rally in support of freedom of Palestinians in the French capital that wasn’t banned on security grounds.
