The UN World Food Program said in a statement that 25 trucks carrying food entered Gaza on Sunday through the Zikim crossing “destined for starving communities in northern Gaza.”

“Shortly after passing the final checkpoint beyond the Zikim crossing point into Gaza, the convoy encountered large crowds of civilians anxiously waiting to access desperately needed food supplies,” the WFP said. “As the convoy approached, the surrounding crowd came under fire from Israeli tanks, snipers, and other gunfire.” The statement added: “These people were simply trying to access food to feed themselves and their families on the brink of starvation.”

On Sunday, the health ministry said that 18 people had died from starvation over the past day. A day earlier, the ministry issued an urgent bulletin saying “unprecedented numbers of starving people of all ages are arriving at emergency rooms in a state of extreme exhaustion and fatigue. We warn that hundreds of those whose bodies have emaciated will be at risk of certain death as a result of starvation and their bodies’ ability to withstand being overwhelmed.” Multiple reports have documented Palestinians sifting through garbage, scraping spilled food from the ground and eating from trash in the streets. The UN estimates that nearly one in three people is not eating for days.
