UN officials said on Sunday real progress was being made with the aid being allowed into Gaza
Eri Kaneko, a spokesperson for the UN's Office for the Coordination of Humanitarian Affairs, said cooking gas supplies have entered Gaza for the first time since March. Other aid moving through include flour, fruit and meat.
She added that officials were also given additional access to move in medical equipment and help move Palestinians from flood-prone areas to safer locations ahead of the winter.
The largest humanitarian actor in Gaza, UNRWA, which has the equivalent of 6,000 trucks of aid waiting outside in Egypt and Jordan, said it had no clarity on its role in the new scaling up of relief provided to Gaza.
Spokesperson Jonathan Fowler said the UN agency for Palestinian refugees is "standing ready" to contribute and has enough food supplies in its warehouses for the entire population of the Gaza Strip for three months.
Associated Press footage showed dozens of trucks crossing the Egyptian side of the Rafah crossing with the Gaza Strip. The Egyptian Red Crescent said they carried medical supplies, tents, blankets, food and fuel.
The trucks will head to the inspection area in the Kerem Shalom crossing for screening by Israeli troops.
Abeer Etifa, a spokeswoman for the World Food Program, said workers were clearing roads inside Gaza Sunday to facilitate delivery.
The Israeli defense body in charge of humanitarian aid in Gaza, COGAT, said that the amount of aid entering the Gaza Strip is expected to increase Sunday to around 600 trucks per day, as stipulated in the agreement.
Egypt said it is sending 400 aid trucks into Gaza Sunday. The trucks will have to be inspected by Israeli forces before being allowed in.
