DEIR AL-BALAH, Gaza Strip — Nearly three dozen trucks entered Gaza on Sunday in the largest aid convoy since the war between Israel and Hamas began, but humanitarian workers said the assistance still fell desperately short of needs after thousands of people broke into warehouses to take flour and basic hygiene products.

The Gaza Health Ministry, controlled by Hamas, said the death toll among Palestinians passed 8,000, mostly women and minors, as Israeli tanks and infantry pursued what Israeli Prime Minister Benjamin Netanyahu called a “second stage” in the war ignited by Hamas’ brutal Oct. 7 incursion.

The toll is without precedent in decades of Israeli-Palestinian violence. Over 1,400 people have died on the Israeli side, mainly civilians killed during the initial attack, also an unprecedented figure.

Communications were restored to most of Gaza’s 2.3 million people Sunday after an Israeli bombardment described by residents as the most intense of the war knocked out phone and internet services late Friday.

Israel has allowed only a trickle of aid to enter. On Sunday, 33 trucks carrying water, food and medicine entered the only border crossing from Egypt, a spokesperson at the Rafah crossing, Wael Abo Omar, said.

After visiting the Rafah crossing, the chief prosecutor of the International Criminal Court called the suffering of civilians “profound” and said he had not been able to enter Gaza. “These are the most tragic of days,” said Karim Khan, whose court has been investigating the actions of Israeli and Palestinian authorities since 2014.

Khan called on Israel to respect international law but stopped short of accusing it of war crimes. He called Hamas’ Oct. 7 attack a serious violation of international humanitarian law. “The burden rests with those who aim the gun, missile or rocket in question,” he said.
