The UN World Food Programme says on X that a lack of supplies forced its teams to stop distributing aid parcels this month.
In the North Gaza governorate, the agency said, the WFP is “no longer able to distribute food in any form”.
It added that in the central and southern Strip, there is currently no aid distribution and bakeries are running out of flour, but hot meal kitchens are still operating in some areas.
In July, UN experts said famine had already arrived in the Gaza Strip.
