UN humanitarian workers say they are hoping that 30 more lorries of food aid will enter northern Gaza today.
Distribution points are still working in some areas, they say, although Jabalia remains impossible to reach because of the ongoing Israeli military offensive, which it says is to target Hamas operatives who are regrouping.
Yesterday evening, the Israeli body which manages crossings into Gaza, COGAT, said that it had allowed in 30 lorries carrying flour and food from the World Food Programme.
That broke a two-week stretch during which the UN says that aid levels completely dropped off.
“The situation is desperate. We have no shelter supplies, very little food and zero assurances from Israel on getting anything into Jabalia where more than 100,000 people are trapped,” says Georgios Petropoulos, head of the UN’s humanitarian agency, OCHA, in Gaza.
About 400,000 Palestinians remain in northern Gaza, according to the UN.
Tens of thousands have been displaced from their homes in the Jabalia area, while others remain stranded amid increasing bombardment and fighting.
