The situation in Gaza City is 'nothing short of cataclysmic', a UN official has told the BBC, as Israeli tanks and troops continue to advance on the third day of a ground offensive. Olga Cherevko, a spokeswoman for the UN's humanitarian office, reported a constant stream of Palestinians heading south but noted that hundreds of thousands remain trapped. The World Health Organization (WHO) has raised alarms over hospitals nearing collapse, as they struggle to receive lifesaving supplies. The Israeli military asserts that their operations aim to dismantle terror infrastructure and secure the release of hostages held by Hamas. However, the offensive targeting one of Gaza’s most populated areas, which was already facing famine, has been met with widespread international condemnation. The UN indicates that since Israel declared its intent to seize Gaza City, at least 200,000 people have fled south, but many lack resources to move safely. Cherevko described seeing devastating scenes during her recent journey to the area, where civilians faced heavy Israeli airstrikes. As challenges mount, the WHO warns that many individuals, including the injured and disabled, are unable to evacuate safely, placing their lives at further risk. The relentless violence has left existing hospital facilities teetering on the brink, as both health and humanitarian needs grow increasingly desperate.
