While punishing the heat of noon, thousands of Palestinians climbed onto the fence and pushed crowds with life-saving supplies to uncover the scale of the humanitarian disaster that Israel’s three-month aid blockade caused to Gaza.

Israeli military gunfire shaking in the background on Tuesday as desperate crowds struggled to reach Israeli-American food distribution points on the first day of operation.

Television footage from Rafa, southern Gaza shows that many people are funneling through a wired corridor into a large open field, with the Gaza Humanitarian Foundation (GHF) bringing aid packaging. Later, when people forced them to force towards the GHF distribution point, desperately hungry Palestinians, including women and children.

A Palestinian father told Al Jazeera: "We have been dying of hunger. We have to feed the children who want to eat. What else can we do? I can do anything to feed them."

"We see people running, we follow them, even if it means adventure, it's terrible. But fear is no worse than hunger."

After thousands of Palestinians rushed into the aid distribution center, the Israeli military said its troops did not point gunfire at them, but fired warning guns in their outside areas. It said in a statement that controls on the situation have been established and aid allocations have been continued as planned.

But Gaza officials accused Israel of failing to manage aid amid widespread hunger and a ruthless bombing of civilians, including children.

"What happened today is a certain evidence of the humanitarian crisis caused by the occupation's failure to pass policies of hunger, attacks and bombing," the Gaza government media office said in a statement after Mayhem.

GHF's ​​aid is a foundation supported by the United States and recognized by Israel, despite allegations that the new organization has no experience or ability to bring relief to more than 2 million Palestinians in Gaza.

The United Nations and aid groups say the organization does not adhere to humanitarian principles and can further replace people from their homes as Palestinians receive assistance from a limited number of allocated sites.

"Reckless, inhumane plan"

UN spokesman Stephane Dujarric said it was "heartbreaking" to see thousands of Palestinians storm the aid scene.

“We and our partners have a detailed, principled, operational good program supported by Member States to receive assistance to the desperate population,” he told reporters. “We continue to emphasize that the meaningful scale of humanitarian action is crucial to avoid famine and meet the needs of all civilians.”

Chaos emphasizes the amazing level of hunger. According to the latest comprehensive food security phase classification report, 1.95 million people (93% of the enclave population) are facing acute food shortages.

For months, aid groups have warned that Israel is using hunger in Gaza as a weapon of war.

Norwegian Refugee Commission spokesman Ahmed Bayram told Al Jazeera that he described the scene in Rafah as "an inevitable consequence of a reckless and inhumane plan".

"These are scenes we've been warning all month. It spreads the chaos. It spreads the chaos. That's the result."

“I think the best thing that can be done right now is to cancel the program, be reversed, and make it possible for American professional humanitarians in the United Nations and NGOs to do our jobs. There is a lot of aid waiting on the border.

GHF, a Swiss entity, was established in February through a post-channel meeting between Israeli-linked officials and commercial figures, and was made the main issuer of aid by Israel. Meanwhile, Israel has blocked the United Nations and other international organizations from providing assistance.

Despite being promoted to a neutral body, the GHF's ​​close ties with Israel have prompted widespread condemnation by the United States. Its former head resigned suddenly this week, citing the foundation's inability to uphold the core humanitarian principles of "neutrality, impartiality and independence."

According to a report from the New York Times, the GHF comes from "a private meeting of like-minded officials, military officers and businessmen, with close ties to the Israeli government."

Israel said its power is not involved in the physical distribution of auxiliary, although it supports the system's use of biometric screening (including facial recognition) to review aid recipients. Palestinians fear this is another Israeli tool of surveillance and repression.

Critics also warned that the structure of the GHF and its aid in southern Gaza are concentrated in Gaza state under the Israeli military plan.

“This is definitely not enough”

Although the former non-leader distribution network operates about 400 sites across the strip, GHF has established only four “Mega Sites” for Gaza’s 2.3 million residents.

In Deir El-Balah in central Gaza, Al Jazeera's Hind Khoudary reported that many of the food packages distributed were not enough to support the family.

Khoudary describes a typical food box with 4 kg (8.8 pounds) of flour, several bags of pasta, two cans of flour beans, a pack of tea bags and some cookies. Other food packaging contains small amounts of lentils and soup.

Although GHF said it distributed about 8,000 food boxes on Tuesday, its restaurant allegedly had 462,000 meals, Khoudary said the rations would last almost a single family for a long time.

"It's definitely not enough, it's not enough to get all the humiliation Palestinians experienced to accept these food packages," she said.
