The trucks contain medicine, medical supplies, and food, according to Khaled Zayed, the head of the ERC in North Sinai.

On Saturday, on the sidelines of Cairo Summit for Peace, Reuters quoted the UN Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinator Martin Griffiths as saying: "I've been hearing this afternoon — but we're in negotiation on it right now — that we may get another convoy tomorrow [Sunday], maybe even slightly bigger, 20 to 30 trucks."

Israel has imposed a total blockade on the strip for 16 days and cut off food, water, and electricity, worsening the already dire humanitarian situation.

After 15 days of the outbreak of war, the Rafah border crossing between Egypt and the Gaza Strip finally reopened on Saturday, following Israeli approval.

This much-anticipated development facilitated a convoy of 20 trucks to transport vital humanitarian aid, including food and medical supplies to reach the 2.3 million Palestinians in the strip.

However, despite this positive step, a significant backlog of hundreds of trucks, sourced from various local and international channels, remains queued on the Egyptian side of the Rafah crossing, awaiting the necessary authorization to proceed to Gaza.

According to remarks by Griffiths to CNN, the strip is in need of a substantial amount of humanitarian aid, at least a hundred trucks per day. He also stressed the importance of ensuring the sustainability of these shipments.

Meanwhile, the Palestinian Ministry of Health reported that the entry of the 20 trucks on Saturday into the blockaded strip represents only three percent of the typical daily influx of health and humanitarian supplies, which used to exceed 600 trucks per day before the Israeli war on Gaza.

Gaza is still facing continued Israeli prevention of fuel, which is necessary for hospital operations, ambulance services, and water generation.

In TV remarks to Al-Arabiya, the media spokesperson of the Palestinian Red Crescent (PRC) stated that the PRC had consumed all the fuel allocated for ambulances, and now they are resorting to the strategic reserves of Al-Quds Hospital, which is also running low.

“We urge the international community and organizations to include fuel in humanitarian aid trucks to ensure the continued operation of hospitals,” she added.

Prior to the crossing of the 20 trucks, President Abdel-Fattah El-Sisi and US President Joe Biden reached an agreement for the sustained entry of humanitarian aid into the Gaza Strip through the Rafah crossing.

Earlier, Egypt's Minister of Foreign Affairs Sameh Shoukry rejected as “unacceptable” any attempts to misrepresent Egypt’s position on the Rafah crossing, asserting that the crossing has never been officially closed by Egypt, but it is not functioning normally after being targeted by Israel four times.

Israel has "unfortunately" not allowed the opening of the Rafah crossing on the Gaza side, Shoukry said adding that it was "preventing aid from entering Gaza.”
