The United Nations’ World Food Programme has run out of food in Gaza, the organization said Friday, two months into Israel’s humanitarian blockade of the besieged enclave.

Israel has carried out daily waves of strikes on Gaza since ending its ceasefire with Hamas. Meanwhile, Israelis took to the streets of Tel Aviv demanding a ceasefire and a deal to return all the remaining hostages held by Hamas.

The World Food Programme said on Friday it had run out of food stocks in Gaza due to the sustained closure of crossings into the enclave, while Gaza authorities said Israeli airstrikes had killed at least 78 people in the past 24 hours.
