UNITED NATIONS, June 5 (Xinhua) -- The world body's proven aid program remains choked despite the suspension for a second day of the Israeli-endorsed new aid scheme for Gaza, UN humanitarians said Thursday.

The UN Office for the Coordination of Humanitarian Affairs (OCHA) said supplies continued to feed into the Kerem Shalom/Karem Abu Salem crossing from the Israeli side but are severely limited in emerging into Gaza. The crossing is the sole UN aid point allowed by Israel.

"Today (Thursday), just over 20 truckloads of supplies, mostly food assistance, as well as some health supplies, were sent to the Israeli side of Kerem Shalom, a number that reflects a limit imposed by the Israeli authorities," OCHA said.

There were no immediate figures on the number of trucks allowed to pick up payloads from the 20 vehicles to transport the supplies into Gaza for UN distribution in local communities.

The new U.S.-run organization, Gaza Humanitarian Foundation, brings aid to a handful of militarized distribution hubs, often distances from local communities as opposed to what UN officials have described as their tried-and-true method of many distribution points in local communities. The UN system avoids forcing thousands to throng in quest of aid. Earlier this week scores of Palestinians were reportedly killed seeking aid from the few new militarized sites.

OCHA said that after 80 days of full blockade on the entry of aid and any other supplies, people in Gaza are starving.

"This demands the urgent opening of all crossings and allowing unimpeded access for humanitarian organizations to deliver aid at scale, through multiple routes, and to all areas where people require assistance," it said.

The office said its aid partners report that more than 90 percent of families in Gaza lack the cash needed to buy what little food remains available on the market. Meat, dairy, vegetables and fruit are nearly absent from people's diets, and eggs have once again disappeared from the market.

OCHA said Israeli authorities continued to deny humanitarian movements on Wednesday that require coordination. Out of 16 attempts to coordinate such movements, five were rejected, including trucking water, retrieving nutrition supplies and relocating fuel stocks.

The office said six other missions failed, either due to impediments or because organizers had to cancel them, which typically happens for security or logistical reasons. The remaining five were completed. They allowed the partners to screen children for malnutrition, provide medical services, and carry out assessments. However, none of them involved the delivery of supplies.

OCHA said the dwindling number of supplies from earlier aid efforts amounts to a trickle.

"This week, partners working on food security report that 14 of them delivered just over 250,000 meals each day," the office said. "This is much less than the 1 million meals that were being distributed daily at the end of April. Half of the community kitchens in Gaza have been forced to stop cooking due to lack of supplies or displacement orders."

OCHA reports that Israeli authorities on Wednesday issued another displacement order, covering 54 neighborhoods across three governorates: North Gaza, Gaza and Deir el-Balah, the second order issued for the same area, representing one-third of the Gaza Strip.

"Overall, since the renewed escalation of hostilities in March, the Israeli military issued 35 displacement orders, forcing more than 640,000 people to flee again, almost every third Palestinian in Gaza," the office said.

Health care partners warn that facilities continue to be attacked. The humanitarian office reiterated that civilians and health care facilities must always be protected.

OCHA said that fuel, generators and spare parts must be allowed to enter Gaza to restore safe and unimpeded access to water.

On the education front, the humanitarians said their colleagues in Gaza report hundreds of learning spaces have been forced to suspend operations due to insecurity or lack of funding. More than 200,000 students and 5,000 teachers have been affected. ■
