Speaking from Gaza City in the north of the occupied territory, Olga Cherevko from the UN aid coordination office, OCHA, said that water pumps had stopped at one site for displaced people there on Wednesday “because there’s no fuel”.

“We are really – unless the situation changes – hours away from a catastrophic decline and a shutdown of more facilities if no fuel enters or more fuel isn’t retrieved immediately,” she told UN News.

In its latest update on the emergency, OCHA said that without the immediate entry of fuel or access to reserves, 80 per cent of Gaza’s critical care units essential for births and medical emergencies will shut down.

More killed seeking aid

The development comes as Gaza’s authorities reported that 15 people had been killed near an aid distribution hub in the centre of the Strip on Thursday.

On Tuesday, unverified videos of another incident circulating on social media showed dead bodies lying in the street near a relief facility in the southern city of Khan Younis, reportedly following artillery fire.

Finding food is a daily challenge for increasingly desperate Gazans who are “simply waiting for food and hoping to find something in order not to watch their children starve in front of their eyes”, Ms. Cherevko explained.

She added: “I spoke with a woman a couple of days ago where she told me that she went with a friend of hers who is nine months pregnant in hopes of finding some food.

Of course, they didn’t manage because they were too afraid to enter areas where there could be incidents like the ones that have been reported over the past few days.”

Search for shelter

Back in Gaza City, OCHA’s Ms. Cherevko said that conditions in shelters in Gaza are now “absolutely horrific” and increasingly crowded – “there are people coming from the north constantly,” the veteran aid worker added, while others are also moving back northwards, likely to be closer to the entry points for aid convoys.

The amount of aid entering Gaza today remains extremely limited and far below the 600 trucks a day that used to reach the enclave before the war began in October 2023. In its latest update, OCHA reported that “starvation and a growing likelihood of famine” are ever-present in the enclave. An estimated 55,000 pregnant women now face miscarriage, stillbirth and undernourished newborns as a result of the food shortages.

Starvation diet

“With the very limited volume of aid that is entering, everyone continues to face starvation and people are constantly risking their lives to try to find something,” Ms. Cherevko continued.

“You eat or [you’re] left with the choice of starving to death.”

After more than 20 months of war, sparked by Hamas-led terror attacks in Israel, 82 per cent of Gaza’s territory is either an Israeli militarized zone or affected by evacuation orders.

Three months since hostilities re-escalated on 18 March, more than 680,000 people have been newly displaced. “With no safe place to go, many people have sought refuge in every available space, including overcrowded displacement sites, makeshift shelters, damaged buildings, streets and open areas,” OCHA said.

UN High Commissioner for Human Rights Volker Türk on Thursday called for “maximum restraint” and reiterated that both Israel and Iran are bound by international humanitarian law.

“The widescale, continuing attacks by Israel across Iran, and the missile and drone strikes launched in response by Iran, are inflicting severe human rights and humanitarian impacts on civilians, and risk setting the whole region ablaze,” he said in a statement.

“The only way out of this spiralling illogic of escalation is maximum restraint, full respect for international law, and return in good faith to the negotiating table,” he stressed.

Appalling collateral damage

The UN rights chief also expressed deep concern over the impact on civilians.

“It is appalling to see how civilians are treated as collateral damage in the conduct of hostilities,” he said, adding that threats and inflammatory rhetoric by senior officials on both sides suggest a “worrying intention” to inflict harm on civilians.

The airstrikes, missile and drone attacks – launched by both Israel and Iran since 13 June – have caused heavy damage to civilian infrastructure and claimed hundreds of lives.  

According to Iranian authorities, at least 224 people have been killed, while human rights groups report significantly higher figures. In Israel, officials report 24 deaths and more than 840 injuries so far.

Widespread panic

Warnings from both governments have also prompted widespread panic among civilians.

Israel’s call for civilians to evacuate on Tuesday triggered panic across Tehran, resulting in heavy traffic jams on highways. Movement has reportedly been hampered across the country by fuel shortages, leading to hours-long queues at petrol stations.

Concern for refugees

The Office of the UN High Commissioner for Refugees (UNHCR) expressed grave concern over the deteriorating humanitarian situation, adding that it is monitoring reports that people are on the move within Iran and that some are leaving for neighbouring countries.

UNHCR Spokesperson Babar Baloch cautioned that the situation remained fluid and hard to verify.

“Iran has long hosted the largest Afghan refugee population in the world. Now, its own people are experiencing devastation and fear,” Mr. Baloch added.

He also emphasised the principle of non-refoulement, calling on neighbouring countries to grant protection to anyone fleeing violence, and not turn them back.

Iran hosts an estimated 3.5 million refugees and those in refugee-like situations, including some 750,000 registered Afghans and over 2.6 million undocumented individuals.

Regional worries

There is already regional fallout, with missile launches from Yemen towards Israel and the Occupied Palestinian Territory and heightened tensions reportedly involving armed groups in Iraq, according to OCHA.

“This escalation takes place as the region already grapples with mounting humanitarian needs, sharply reduced funding, and constrained operational space for humanitarian action,” the Office said in a flash update issued on Wednesday.

“De-escalation is vital to preventing further suffering of civilians and population displacements,” OCHA underscored.
