On Sunday, the Israeli military began actions that it said would improve the “humanitarian response” in Gaza and disprove “the false claim of deliberate starvation”.
Israel announced there would be a “local tactical pause” in three areas of Gaza for 10 hours a day, as well the establishment of “designated secure routes” for aid convoys.
The military also allowed aid drops carried out by foreign countries to resume, despite humanitarian agencies warning that the method was ineffective and dangerous.
Israeli military body Cogat, which co-ordinates the entry of aid into Gaza, said more than 120 lorry loads of aid were collected from crossings by the UN and other international organisations on Sunday, and that hundreds more lorry loads were awaiting collection.
Mr Fletcher said the UN had collected fewer than 100 lorry loads in that time, and noted that 600 to 700 loads had entered Gaza daily on average during the two-month ceasefire between Israel and Hamas at the start of this year.
Asked to respond to Israel’s criticism of UN agencies for not collecting aid from crossings, he said: “We’re not going to leave on pallets if we can. But to get to it our drivers face bureaucratic constraints, they face massive security constraints.”
He also said that most of the UN’s food lorries were looted after entering Gaza on Sunday.
“Most of those lorries… were hit by desperate individual civilians, starving. The flour was taken off those lorries and its very, very dangerous for our drivers.”
Mr Fletcher also warned that UN teams on the ground believed the Israeli military’s pauses would only last a week or so, which he said would be “clearly insufficient when before our eyes we’re seeing this 21st Century atrocity on the ground”.
“We need a sustained period of delivery – weeks, months – to build up, to stop that starvation and build up the supplies again. Ultimately, we need a ceasefire. Pauses are a good step in the right direction, but stopping the conflict is the key.”
On Sunday, the World Health Organization warned that malnutrition was “on a dangerous trajectory in the Gaza Strip, marked by a spike in deaths in July”.
Of the 74 malnutrition-related deaths in Gaza in 2025, 63 had occurred this month, including 24 children under five and one child over five, the UN agency said.
“Most of these people were declared dead on arrival at health facilities or died shortly after, their bodies showing clear signs of severe wasting,” it added.
The WHO said the crisis was “entirely preventable” and condemned what it called the “deliberate blocking and delay of large-scale food, health, and humanitarian aid”.
Hamas has denied stealing aid, and on Sunday the New York Times cited senior Israeli military officials as saying that the military had never found proof that the armed group had systematically stolen aid from the UN. Reuters news agency also reported last week that US government analysis found no evidence of systematic theft by Hamas of US-funded aid.
Netanyahu on Sunday savaged claims that Israel was deliberately starving civilians in Gaza, which would amount to a war crime.
“What a bold-faced lie. There is no policy of starvation in Gaza, and there is no starvation in Gaza.” he said.
“We enable humanitarian aid throughout the duration of the war to enter Gaza. Otherwise, there would be no Gazans. And what has interdicted the supply of humanitarian aid is one force, Hamas. Again, the reversal of truth,” he added.
Netanyahu said the Israeli military’s humanitarian pauses and corridors meant the UN had “no excuses left” not to collect and distribute all the aid from the crossings.
“Stop lying. Stop finding excuses. Do what you have to do.”
On Monday, local hospital sources said Israeli attacks across Gaza had killed more than 30 people, including aid seekers.
The Israeli military launched a campaign in Gaza in response to the Hamas-led attack on southern Israel on 7 October 2023, in which about 1,200 people were killed and 251 others were taken hostage.
At least 59,821 people have been killed in Gaza since then, according to the territory’s Hamas-run health ministry.
