The UN’s World Food Programme (WFP) has said it began delivering food in the Gaza Strip, but that it is not enough, Al Jazeera reports.

In a statement, it called on the Israeli authorities to allow at least 100 aid trucks per day through the northern, central, and southern border points.

WFP said that they have been able to dispatch dozens of aid convoys since May 21, but despite this, the food delivered to date is still “a tiny fraction of what a population of over two million people need to survive”.

It also stated that a recent WFP assessment found that nearly one person in three is not eating for days at a time.

Some 470,000 people are expected to face catastrophic hunger between May and September this year, it said, adding that flour for bread is 3,000 times more expensive than before the conflict, and cooking oil is unavailable.
