JERUSALEM — Israel’s cutoff of food, fuel, medicine and other supplies to Gaza’s 2 million people has sent prices soaring and humanitarian groups into overdrive trying to distribute dwindling stocks to the most vulnerable.

The aid freeze has imperiled the progress aid workers say they have made to stave off famine over the past six weeks during Phase 1 of the ceasefire deal Israel and Hamas agreed to in January.

After more than 16 months of war, Gaza’s population is entirely dependent on trucked-in food and other aid. Most are displaced from their homes, and many need shelter. Fuel is needed to keep hospitals, water pumps, bakeries and telecommunications — as well as trucks delivering the aid — operating.

Israel says the siege aims at pressuring Hamas to accept its ceasefire proposal. Israel has delayed moving to the second phase of the deal it reached with Hamas, during which the flow of aid was supposed to continue. Israeli Prime Minister Benjamin Netanyahu said Tuesday that he is prepared to increase the pressure and would not rule out cutting off all electricity to Gaza if Hamas doesn’t budge.

Rights groups have called the cutoff a “starvation policy.”

Food, Fuel and Shelter Supplies Are Threatened

The World Food Program, the U.N.’s main food agency, says it has no major stockpile of food in Gaza because it focused on distributing all incoming food to hungry people during Phase 1 of the deal. In a statement to AP, it said existing stocks are enough to keep bakeries and kitchens running for under two weeks.

WFP said it may be forced to reduce ration sizes to serve as many people as possible. It said its fuel reserves, necessary to run bakeries and transport food, will last for a few weeks if not replenished soon.

There’s also no major stockpile of tents in Gaza, said Shaina Low, communications adviser for the Norwegian Refugee Council. The shelter materials that came in during the ceasefire’s first phase were “nowhere near enough to address all of the needs,” she said.

“If it was enough, we wouldn’t have had infants dying from exposure because of lack of shelter materials and warm clothes and proper medical equipment to treat them,” she said.

At least seven infants in Gaza died from hypothermia during Phase 1.

Urgently Checking Reserves

“We’re trying to figure out, what do we have? What would be the best use of our supply?” said Jonathan Crickx, chief of communication for UNICEF. “We never sat on supplies, so it’s not like there’s a huge amount left to distribute.”

He predicted a “catastrophic result” if the aid freeze continues.

During the ceasefire’s first phase, humanitarian agencies rushed in supplies, with about 600 trucks entering per day on average. Aid workers set up more food kitchens, health centers and water distribution points. With more fuel coming in, they could double the amount of water drawn from wells, according to the U.N. humanitarian agency.

Around 100,000 tents also arrived as hundreds of thousands of Palestinians tried to return to their homes, only to find them destroyed or too damaged to live in.

But the progress relied on the flow of aid continuing.

Oxfam has 26 trucks with thousands of food packages and hygiene kits and 12 trucks of water tanks waiting outside Gaza, said Bushra Khalidi, Oxfam’s policy lead in the West Bank.

“This is not just about hundreds of trucks of food, it’s about the total collapse of systems that sustain life,” she said.

The International Organization for Migration has 22,500 tents in its warehouses in Jordan after trucks brought back their undelivered cargo once entry was barred, said Karl Baker, the agency’s regional crisis coordinator.

The International Rescue Committee has 6.7 tons of medicines and medical supplies waiting to enter Gaza and its delivery is “highly uncertain,” said Bob Kitchen, vice president of its emergencies and humanitarian action department.

Medical Aid for Palestinians said it has trucks stuck at Gaza’s border carrying medicine, mattresses and assistive devices for people with disabilities. The organization has some medicine and materials in reserve, said spokesperson Tess Pope, but “we don’t have stock that we can use during a long closure of Gaza.”

Prices Up Sharply

Prices of vegetables and flour are now climbing in Gaza after easing during the ceasefire.

Sayed Mohamed al-Dairi walked through a bustling market in Gaza City just after the aid cutoff was announced. Already, sellers were increasing the prices of dwindling wares.

“The traders are massacring us, the traders are not merciful to us,” he said. “In the morning, the price of sugar was 5 shekels. Ask him now, the price has become 10 shekels.”

In the central Gaza city of Deir Al-Balah, one cigarette priced at 5 shekels ($1.37) before the cutoff now stands at 20 shekels ($5.49). One kilo of chicken (2.2 pounds) that was 21 shekels ($5.76) is now 50 shekels ($13.72). Cooking gas has soared from 90 shekels ($24.70) for 12 kilos (26.4 pounds) to 1,480 shekels ($406.24).

Following the Oct. 7, 2023, Hamas attack on Israel, Israel cut off all aid to Gaza for two weeks — a measure central to South Africa’s case accusing Israel of genocide in Gaza at the International Court of Justice. That took place as Israel launched the most intense phase of its aerial bombardment of Gaza, one of the most aggressive campaigns in modern history.

Palestinians fear a repeat of that period.

“We are afraid that Netanyahu or Trump will launch a war more severe than the previous war,” said Abeer Obeid, a Palestinian woman from northern Gaza. “For the extension of the truce, they must find any other solution.”
