At least four people were killed after hundreds of anguished and hungry Palestinians stormed a United Nations food warehouse.
Hundreds of Gazans raided the warehouse on Wednesday in a desperate attempt to grab something to eat.
They shoved one other and even ripped off pieces of the building in Zawaida, central Gaza to get inside, witnesses said.
Two people were fatally crushed in the crowd, while two others died of gunshot wounds, a local hospital said.
It was not immedialtely clear who fired the shots.
The deaths came a day after dozens of Palestinians were fired upon while overrunning a new aid-distribution site.
The UN World Food Programme said the humanitarian situation in Gaza had spiralled out of control after almost three months of Israeli blockade, with only limited aid allowed in recently.
A statement said: “Humanitarian needs have spiralled out of control after 80 days of complete blockade of all food assistance and other aid into Gaza. Gaza needs an immediate scale-up of food assistance. This is the only way to reassure people that they will not starve.”
The Israeli and US-backed Gaza Humanitarian Foundation (GHF) has been slated to take over aid operations in the besieged territory.
But humanitarian organisations have rejected the new system, arguing it will fail to meet the needs of Gaza's 2.3 million people and that it will allow Israel to use food to control the population.
One person was killed and 48 others injured on Tuesday after a crowd overwhelmed the hub in Khan Younis, southern Gaza.
Ajith Sunghay, head of the UN Human Rights Office in the Occupied Palestinian Territory, alleged that Israeli army gunfire had caused most of the injuries.
The Red Cross Field Hospital said those who were hurt suffered gunshot wounds, including women and children.
However, the IDF — which guards the site from a distance — claimed it only fired warning shots to control the situation, while the GHF said its military contractors did not pull the trigger.
Meanwhile, Prime Minister Benjamin Netanyahu said his nation’s forces killed Mohammed Sinwar, the brother of former Hamas leader Yahya Sinwar, the mastermind of the October 7 massacre.
The siblings were reportedly together during the massacre, which killed 1,200 people with around 250 others taken hostage.
Israel's response has killed more than 54,000 Palestinians, according to Gazan health officials, and destroyed much of the coastal territory.
Speaking before parliament, Mr Netanyahu said Mohammed died in a recent airstrike in Gaza, seven months after Yahya was eliminated during a chance encounter in Rafah.
In other developments, Israel carried out strikes on the Sanaa International Airport in Yemen, destroying the last plane belonging to the country's flagship airline Yemenia, which was used by Iran-backed Houthi rebels.
