The UN’s humanitarian agency (OCHA) said Israel has denied or impeded all of its attempts to provide food and healthcare to tens of thousands of people trapped in besieged northern Gaza so far this month.

The agency said Israeli authorities allowed only one mission by the World Food Program (WFP) to enter on November 11, according to Al Jazeera. 

The WFP convoy included two trucks carrying life-saving ready-to-eat rations and wheat flour, and one truck carrying bottled water. The aid was delivered to the Mahdia al-Shawwa School, which was sheltering displaced Palestinians, and a nearby public shelter, OCHA said.

But shortly afterwards, Israeli forces surrounded the area, shelled it and forced people to flee.

Earlier, Palestinian media reported that Israeli forces had set fire to Mahdia al-Shawwa School and destroyed the building.
