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.

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.
