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.

Food security experts say the Gaza Strip is at critical risk of famine if Israel doesn’t lift its blockade and stop its military campaign.

Israel’s government has publicly dismissed warnings of extreme food shortages after it blocked aid deliveries, but an internal analysis concluded that a crisis looms if food supplies are not restored.
