The United Nations has warned that Gaza is experiencing its most severe humanitarian crisis since the outbreak of the latest round of the Israel-Hamas conflict in October 2023, blaming Israel for blocking aid and violating international law. At a press conference on Monday, the United Nations issued a stark warning about the humanitarian catastrophe unfolding in Gaza, saying that the situation has reached its worst point since the outbreak of hostilities 18 months ago. "The Office for the Coordination of Humanitarian Affairs (OCHA) warns that the humanitarian situation is now likely to be the worst it has been in the 18 months since the outbreak of hostilities. It has now been a month and a half since any supplies were allowed through the crossings into Gaza, by far the longest such halt to date. Humanitarian aid should be above any sort of political decisions. And I think there have been Security Council resolutions, and I think we've been very clear on the fact that humanitarian aid should be freely accessible to all who need it," said Stephane Dujarric, spokesman for the UN secretary-general. "Israel has responsibilities under international law as the occupying power to adequately provide basic services and humanitarian aid to the people of Gaza. That is not happening. We will point out the situations, the violations of, we feel, the international law," Dujarric added. According to UN staff on the ground, Israeli attacks in Gaza have intensified in recent days, resulting in high civilian casualties and further damage to Gaza's already fragile infrastructure. Over half of Gaza's wells are now inoperable, and more than 70 percent of the territory has been designated as evacuation or danger zones following new Israeli orders. Even UN facilities haven't been spared by Israeli attacks. Warehouses and food distribution centers operated by the United Nations in Gaza City have reportedly come under attack.
