Gaza is on the brink of famine, UN Secretary-General Antonio Guterres said Tuesday, citing a new report showing alarming levels of hunger and malnutrition. “This is not a warning—it’s happening now,” he said, according to Xinhua.

The UN’s food security alert found two out of three famine thresholds breached in parts of Gaza, with over 20,000 children treated for acute malnutrition since April and rising hunger-related deaths.

Guterres called for a permanent ceasefire, full humanitarian access, and a major increase in aid. While a temporary pause has allowed limited supplies in, UN officials say ongoing restrictions and looting prevent much of it from reaching those in need.

“A trickle of aid is not enough,” Guterres said. “This crisis demands urgent, united action”, Xinhua reported.
