LIKE many in northern Gaza, Shadi Jenina, 40, has resorted to desperate measures to stave off hunger for his five children: grinding up animal feed into flour.
"We're looking for food for birds, animals and livestock... such as barley, corn, wheat and fodder. We grind them and make flour," Jenina said.
"The bread is dry and not suitable for humans but we're forced to eat it," he said, adding
that they struggle to feed their children.
The Gaza Strip was one of the poorest places in the Middle East even before Israel declared a complete siege on the territory after Hamas' Oct 7 attack.
Though much of Gaza was reliant on food aid, enough of it was entering the territory to largely meet the needs of its 2.4 million inhabitants.
But now, after more than four months of war that has flattened huge swathes of the Strip, Gazans are inching closer towards famine, according to the United Nations's World Food Programme.
And the situation in the north of the coastal territory is particularly acute, with international aid agencies unable to get in.
Since the start of this year, Israel has given permission to only 12 out of 77 United Nations evaluation missions to assess the needs of people in northern Gaza.
"There are about 300,000 people in the north and I have no idea how they've survived," said Andrea De Domenico, head of the UN humanitarian agency OCHA in the Palestinian territories.
"What we managed to bring up there is not enough. It is pure misery.
"Repeatedly, when we are allowed to cross the checkpoint at Wadi Gaza to deliver food assistance, thousands of people block and unload the trucks at the risk of being shot."
In the last few days, the non-profit organisation World Central Kitchen, which made thousands of meals a day, said it had been forced to leave Gaza City for Rafah in the south.
Rafah, on the border with Egypt, has been turned in recent weeks to a vast camp for some 1.4 million people, most of them displaced by Israel's relentless bombing.
Israel, though, is preparing a ground invasion of Rafah, prompting fears of a bloodbath.
As Egypt refuses to house Palestinian civilians on its side of the border, the question now is how to move more than a million people back towards the north to prevent them from getting caught up in fighting.
OCHA's De Domenico said: "There is no short-term solution... what's clear for the short term is that a ground invasion in Rafah would have dangerous consequences."
Before the war, some 500 trucks carrying a range of goods entered Gaza every day.
Since then, the numbers rarely go beyond 200, despite the enormous demand.
Israel has tightened checks on lorries coming into the territory to prevent arms being brought to Hamas, and the group's leaders leaving, all of which restricts the flow of aid.
At the same time, far-right Israeli groups have blocked trucks at the entry point to Gaza, while the UN also has to have explosives experts on board because of unexploded ordnance in the north.
"We're going to die from hunger, not by bombs or missiles," said Mohammed Nassar, 50, from Jabalia in northern Gaza. "The biggest problem is that everything that is available is expensive and we don't have the money."
The price of 1kg of tomatoes, for example, has shot up past 50 shekels, more than 20 times its cost before the war. Flour has doubled in price from 35 to 70 shekels, he added.
"We need food now," said Nassar. "Children are dying from hunger. How is this our fault or theirs?"
