DEIR AL-BALAH, Gaza Strip — Rains drenched Gaza’s tent camps and dropping temperatures chilled Palestinians huddling inside them Thursday as winter storm Byron descended on the war-battered territory, showing how two months of a ceasefire have failed to sufficiently address the spiraling humanitarian crisis there.

Families found their possessions and food supplies soaked inside their tents. Children’s sandaled feet disappeared under opaque brown water that flooded the camps, running knee deep in some places. Dirt roads turned to mud. Piles of garbage and sewage cascaded like waterfalls.

“We have been drowned. I don’t have clothes to wear and we have no mattresses left,” said Um Salman Abu Qenas, a displaced mother in a Khan Younis tent camp. She said that her family couldn’t sleep the night before, because of the water in the tent.

Aid groups say not enough shelter materials are getting into Gaza during the truce. Figures recently released by Israel’s military suggest it hasn’t met the ceasefire stipulation of allowing 600 trucks of aid into Gaza a day, though Israel disputes that finding.

“Cold, overcrowded, and unsanitary environments heighten the risk of illness and infection,” the U.N. agency for Palestinian refugees, UNRWA, said on X. “This suffering could be prevented by unhindered humanitarian aid, including medical support and proper shelter.”

Sabreen Qudeeh, also in the Khan Younis camp, in a squalid area known as Muwasi, said that her family woke up to rain leaking from their tent’s ceiling and water from the street soaking their mattresses.

“My little daughters were screaming,” she said.

Ahmad Abu Taha, also living in the camp, said there wasn’t a tent that escaped the flooding. “Conditions are very bad, we have old people, displaced, and sick people inside this camp,” he said.

Floods in south-central Israel trapped more than a dozen people in their cars, according to Hebrew media. Israel’s rescue services, MDA, said that two young girls were slightly injured when a tree fell on their school.

The contrasting scenes with Gaza made clear how profoundly the Israel-Hamas war had damaged the territory, destroying the majority of homes. Gaza’s population of around 2 million is almost entirely displaced, and most people live in vast tent camps stretching along the coast, or set up among the shells of damaged buildings without adequate flooding infrastructure and with cesspits dug near tents as toilets.

At least three buildings in Gaza City already damaged by Israeli bombardment during the war partially collapsed under the rain, Palestinian Civil Defense said. It warned people not to stay inside damaged buildings, saying they too could fall down on top of them.

The agency also said that since the storm began, they have received more than 2,500 distress calls from people across Gaza whose tents and shelters were damaged.

With buckets and mops, Palestinians laboriously scooped water out of their tents.
