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 during a recent visit, while underscoring that hundreds of thousands remain in the city.

The World Health Organization (WHO) has cautioned that hospitals are overwhelmed and on the brink of collapse due to the continuous fighting and restrictions on lifesaving supplies. The Israeli military stated its operations target dismantling Hamas's infrastructure and rescuing hostages held in the densely populated area that previously housed around one million individuals amid a confirmed famine.

Widespread international condemnation has emerged against Israel's military strategy, which impacts a region already saturated with civilians. Witnesses have observed heavy bombardment and troop movements across key neighborhoods. As the hostilities escalate, the humanitarian crisis deepens, with many unable to access even basic shelter or medical care.

Dr. Tedros Adhanom Ghebreyesus, the chief of WHO, highlighted the gravity of the situation where injured individuals cannot move to safety, leading to catastrophic conditions.

The UN reports that at least 200,000 people have fled from northern to southern Gaza since mid-August, yet the journey has proven perilous and situated families often end up without shelter. Aid organizations continue to call for urgent humanitarian access as the toll of violence rises, exacerbating the stresses on medical facilities.

As Israel expands its military actions, the international community faces growing pressure to address the humanitarian fallout, which sees women giving birth in the streets and families struggling for mere survival.
