The development in Gaza prompted the UN Secretary-General António Guterres to express himself with unusual sharpness in criticism directed directly at Israel's warfare.
The Palestinians in Gaza are exposed to what may be the most brutal phase of a brutal conflict, said Guterres in a statement outside the Security Council at the UN headquarters in New York on Friday.
For nearly 80 days, Israel has blocked the supply of life-saving international aid. The entire population of Gaza is threatened by starvation. The Israeli military offensive is intensifying with horrific levels of death and destruction, he continued.
Criticizes the system
The convoys that entered Gaza on Thursday via the Kerem Shalom border crossing underwent "a thorough security check", announced Israel's military on Friday.
On board were food, flour, medicine, and medical equipment, writes the newspaper Haaretz. It is unclear how much of the deliveries have so far reached those in need.
On Friday, the UN's food program (WFP) reported that 15 of the trucks had been looted on their way to bakeries in the south of Gaza during the night.
WFP criticizes the system with a very limited number of bakeries and places where Gaza's population can access food.
"A drop in the ocean"
"These trucks transported critical supplies to starving people who anxiously await assistance. Hunger, desperation, and uncertainty about whether more food will come, contribute to increased insecurity", they write in a statement, according to Haaretz.
WFP demands that the Israeli authorities enable a significantly larger and more consistent flow of emergency aid, as well as that the transportation takes place via safer routes.
Israel resumed emergency aid deliveries to Gaza on Monday, after a nearly three-month-long blockade that has prompted the UN and organizations to warn of an imminent mass starvation in Gaza.
The trucks that have so far been allowed in are, according to the UN, "a drop in the ocean.
