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.

Half a million people in the Gaza Strip face starvation, a global hunger monitor said on Monday, saying the Israeli-blockaded enclave still confronts a critical risk of famine with a high risk of one occurring by the end of September.
