The World Food Programme (WFP) says it hasn’t been able to bring any food aid into Gaza since March 2 because of Israel’s closure of all crossing points for both humanitarian and commercial supplies, Al Jazeera reports.

Current food stocks in Gaza will be able to support active kitchens and bakeries for up to one month, while ready-to-eat food parcels can support 550,000 people for two weeks, it said.

The UN agency also said it’s increasingly concerned about food shortages in the occupied West Bank where military activity, displacement, and movement restrictions are disrupting markets and limiting access to food.

“These disruptions and the worsening economic conditions over the last year are putting upward pressure on prices,” it said. “With rising displacement and unemployment even basic food items have become unaffordable for many families.”
