Hundreds of thousands of displaced people in Gaza are facing severe flooding after heavy rains, with emergency shelter materials blocked from entering the area, according to the United Nations International Organization for Migration. The agency warns that nearly 795,000 people are at risk in low-lying, rubble-filled areas, where makeshift shelters are unsafe and drainage is poor, raising concerns about disease outbreaks. Materials needed to reinforce shelters and prevent flooding, such as timber, sandbags, and water pumps, have been delayed due to access restrictions. While Israel claims it is fulfilling its obligations and criticizes aid agencies, the Defense Ministry body responsible for humanitarian matters did not comment. Supplies already sent, including waterproof tents and tarpaulins, have proven inadequate against the flooding, leaving families struggling to protect their children.
