The limited access to the part of the Gaza enclave is posing serious challenges to the UN organisations' aid delivery mechanism, as much of North Gaza has remained cut off since the truce deal.
The aid organisations, including the World Food Programme, have called for more aid vehicles to be allowed into the Gaza Strip.
On Friday, the UN urged Israeli authorities to hasten the opening of border crossings into the Gaza Strip, saying it will take some time to scale up the efforts to thwart the famine situation in the enclave.
Since the ceasefire agreed on Monday this week, the UN has delivered nearly 3,000 tonnes of food, but acknowledged that it will take time to "flood Gaza with food".

Israel has banned international aid organisations from entering the Gaza Strip since the resumption of fighting in March this year.
Tom Fletcher, the UN's humanitarian head, said in a social media video published Friday, "We've begged for this access for months and finally we're seeing goods moving at scale: food, medicine, tents, fuel … a lot of fuel got in today."
World Programme spokesperson Abeer Etefa said, “The ongoing ceasefire has opened a narrow window of opportunity. WFP is moving very quickly and swiftly to scale up food assistance and reach families who have endured months of blockade, displacement and hunger.”
She said that the WFP has been able to deliver “300 truckloads of aid to Gaza. We are still below what we need, but we're getting there." Meanwhile, on Friday, the IDF confirmed receiving three more bodies of the hostages, bringing the total number to 31, along with 20 living hostages freed by Hamas since Monday.
