Gazans remain at “critical risk of famine,” UN-backed food security experts warned on Monday, a full 19 months since war began with Israel and 70 days since deliveries stopped of all aid and commercial supplies.

One in five people in the Gaza Strip are facing starvation as the entire territory edges closer to famine, a new United Nations-backed report warns, after nearly three months of Israel’s blockade of critically needed humanitarian aid.

Roughly 500,000 Palestinians are experiencing “catastrophic” hunger levels, the latest food insecurity report finds.
