The U.N. food agency says Palestinians in the Gaza Strip have blocked and offloaded dozens of food trucks as desperation mounts following Israel’s monthslong blockade and airstrikes.

Israel is blocking all but a trickle of humanitarian aid from entering Gaza, the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) said, with almost no ready-to-eat food entering what its spokesperson described as "the hungriest place on earth".

Israel is facing growing international pressure as aid distribution efforts in Gaza devolved into chaos during the first days of a controversial new mechanism backed by the United States and Israel.
