[The] U.N. World Food Programme estimates that at least 300 trucks of food are needed every day to meet the basic needs of the population. During the first half of March, an average of 159 trucks a day have entered Gaza, representing 40% of the minimum amount required, according to U.N. data. Before the Israeli offensive, an average of 500 trucks entered every working day, including fuel trucks.
Israel was tightly controlling the amount of calories per capita that entered the strip long before Oct 7 even happened. Their justification was that any excess would provide Palestinians with a stockpile that would make any future sieges less effective. They weren’t even allowed to collect rainwater.
