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.

The entire population of Gaza is at “critical risk of famine,” according to a report published Monday by the UN-backed Integrated Food Security Phase Classification.

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.
