Five children were among 20 killed overnight Wednesday when a building – damaged in Israel's genocidal war on Gaza – came crashing down on dozens of Palestinians sheltering there.
The incident highlights the ongoing danger for tens of thousands of Palestinians who live in an estimated 2,000 damaged buildings due to Israeli airstrikes across coastal enclave.
Rescue workers from the civil defense said at least 20 people, including five children, were killed and 14 others injured when the seven-story building collapsed. Nearly 100 more people were believed to be trapped under the rubble.
A video obtained by Reuters showed rescue workers trying to pull out two people from under a collapsed wall. Another video circulated on social media showed Gaza's civil defense spokesperson, Mahmoud Basal, carrying a little girl, wrapped in a blood-stained scarf, in his hands.
Raed al-Dahshan, the director of Gaza City's civil defense service, said at least 10 families lived in the collapsed building and there was still hope of finding survivors.
"We are still hearing voices from under the rubble, so there is still hope to find people," said Dahshan.
Alessandro Mrakic, head of the U.N. Development Programme's Gaza office, said rescuers from some U.N. agencies were taking part in the rescue efforts, which he described as difficult due to the lack of proper machinery. Egypt's relief agency was also taking part in rescue efforts.
"The situation, as you see, is tragic because we don't have the equipment and machinery that is needed. So there are actually people that are digging with their bare hands. We need to prepare (for more deaths)," said Mrakic.
"There are approximately 400 buildings at risk of collapse. And we know that these buildings will collapse, especially now with the upcoming winter," he added.
Palestinian and U.N. officials blame Israel's restrictions on Gaza for the lack of heavy machinery in the territory. Israel says its curbs aim to keep equipment out of the hands of Hamas.
Israel's genocidal war on Gaza – launched after the Hamas incursion into Israel in October 2023 – has generated around 61 million tons of wreckage and debris that could take seven years to clear, according to the United Nations.
Dahshan warned residents to stay away from wrecked buildings due to the risk of collapse. The local rescue service says about 2,000 damaged buildings are inhabited by families.
"The limited availability of shelter options forced residents to move into this building, believing it was safe. However, at one point it collapsed entirely, tragically crashing down on people as they slept," said Dahshan.
Many families have told Reuters in the past months that they resorted to living in partially damaged buildings to protect themselves against wind and rainstorms, and because of the lack of new tents for the homeless.
An October 2025, U.S.-backed cease-fire halted large-scale fighting in Gaza, but it Israeli has carried out daily strikes and there has been little progress on steps toward permanent peace.
Hamas accuses Israel of violating the truce and undermining efforts to implement U.S. President Donald Trump's broader plan to end the Gaza conflict, which includes an Israeli withdrawal from the Gaza Strip and the disarmament of Hamas.
Israel says Hamas has been violating the deal.
More than 1,300 Palestinians, mostly civilians, have been killed in Gaza since the cease-fire took effect, according to the territory's health officials, while the Israeli military says four if its soldiers have died.
