Fuel in Gaza is running out, forcing hospitals to ration power, water systems to fail, and ambulances to stall, the UN said Tuesday. The few supplies left are being used for critical services like intensive care and water desalination but even those are nearly gone.

The UN’s humanitarian office (OCHA) warned that deaths could rise quickly unless Israel allows fuel in immediately and regularly. Ongoing strikes continue to hit shelters, schools, and medical sites, with many people killed or injured daily, according to UN News.

New Israeli orders are forcing more people to move again, cramming families into shrinking, unsafe zones that now cover just 15 percent of Gaza. Basic services are nearly non-existent, and people are struggling to find food and protect their children.

The World Health Organization said Nasser Hospital in Khan Younis is overwhelmed, working beyond capacity with severe shortages of medicine, supplies, and fuel. Many patients arrive after being shot while trying to get food, UN News reported.

Humanitarian access remains heavily blocked, with most aid missions either denied or disrupted.
