People in Gaza have been describing their struggle to access food and other essential supplies, as the UN condemns the Israel-backed aid distribution system
"I can't hold on any longer," one teenager tells the BBC, while a mother speaks of having no food for her children
Some 33 people, including 12 children, have died from malnutrition in the past 48 hours, according to Gaza's Hamas-run health ministry
Gaza's "last lifelines" are collapsing, with humanitarian conditions breaking down at an "accelerating" pace during Israel's offensive, the UN chief says
The UN's Human Rights Office says more than 1,000 people have been killed seeking food since Israel's new aid method began on 27 May - Israel says the system is necessary to stop Hamas stealing aid

Lammy now announces an extra £40m of humanitarian assistance to Gaza this year.
This will include £7.5m for humanitarian medical aid charity UK-Med to sustain their "vital operations" in Gaza and save more lives, he adds.
Lammy reiterates news from earlier that he joined dozens of other foreign ministers as signatories to a joint statement, calling for an end to the war with a "simple message".
"The war in Gaza must end now," he says adding that "there is no military solution".
"The next ceasefire must be the last ceasefire."
Lammy then thanks the US, Qatar and Egypt for diplomatic efforts.
Image source, House of CommonsLammy says that Israel's defence minister Israel Katz proposes "driving Gaza's entire population into Rafah" and "imprisoning Palestinians unless persuaded to emigrate".
"This is a cruel vision that must never come to pass," he says, adding that he condemns it unequivocally.
Israeli Prime Minister Benjamin Netanyahu "should listen to the Israeli people - 82% of whom desperately want a ceasefire", Lammy says.
He adds that Netanyahu should also listen to the hostage families.
"Those hostages may be hidden in cramped tunnels under the ruins of Gaza but we will not forget them, or Hamas's despicable actions, and we will continue to demand their unconditional release," Lammy continues.
"This offensive puts them in grave danger, but still Netanyahu persists."
Lammy adds: "The Israeli government must answer what possible military justification can there be for strikes that have killed desperate starving children."
He then asks what immediate actions Israel is taking to stop "this litany of horrors" and what they will do to hold those responsible to account.
Lammy says he supports Israel's security and right to exist but believes its actions are "doing untold damage to Israel's standing in the world and undermining its long-term security".
Lammy tells MPs there are "daily reports" of Israeli troops opening fire on people waiting to access food in Gaza.
Strikes have hit women and children waiting for a health clinic to open, and an Israeli drone has struck down children filling water containers, he says, adding that Israeli officials have "blamed this on a technical error".
"Hamas is contributing and taking advantage of it," Lammy adds.
"I utterly condemn the killing of civilians seeking to meet their basic needs."
Lammy says the new Israeli aid system in Gaza is "inhumane, dangerous and deprives Gazans of human dignity".
"It contradicts long-established humanitarian principles," he says, adding that it "forces desperate civilians, children among them, to scramble unsafely for the essentials of life".
"It's a grotesque spectacle wrecking a terrible human cost."
Foreign Secretary David Lammy starts by recapping the recent violence in southern Syria, saying the UK government is "horrified", adding that it is "backing a sustainable ceasefire".
Lammy now moves on to speak about the war in Gaza.
He says it has been two-and-a-half months since Benjamin Netanyahu restarted offensive operations in Gaza.
He adds that the Israeli army has driven Palestinians out of 86% of Gaza leaving two million people trapped within an area of 20 square miles.

Image source, ReutersThe controversial Gaza Humanitarian Foundation (GHF) has appealed to UN aid agencies to join its food delivery operation in Gaza, but at the same time blamed the UN for failing to deliver supplies across the strip.
Hundreds of Palestinians have reportedly been killed at GHF distribution sites in recent weeks – UN aid agencies have refused to work with the foundation, describing it as politicised and militarised.
Experienced aid workers warned from the start that the GHF’s model was fraught with risk – it uses armed security guards, it is clearly linked to Israel, and the IDF is positioned around its few distribution sites.
The foundation supplies basic food, but not enough for a population reportedly on the verge of starvation, and no medicines, soap, or baby formula.
Meanwhile UN agencies, who delivered across Gaza during the ceasefire earlier this year, say their supplies are repeatedly blocked.
The GHF says it wants to work with other aid agencies – the UN has refused, and now 25 nations, including Britain, have called for an immediate ceasefire, condemning what they said was Israel’s denial of humanitarian assistance, and describing it as the drip feeding of aid and the inhumane killing of civilians trying to get food.

This afternoon's statement from the UK and dozens of other countries calling for an end to the war in Gaza describes the killing over 800 Palestinians trying to receive humanitarian aid as "horrifying".
There are almost daily reports of Palestinians being killed while seeking aid since the Israeli and US-backed Gaza Humanitarian Foundation (GHF) began to distribute aid in late May. Both Israel and the GHF have disputed death tolls, recorded by the Hamas-run health ministry in Gaza, however the ministry's figures are widely seen as a reliable count of bodies seen by Gazan hospitals.
Some of the deadliest incidents in recent days include:
At the end of June, when the death toll at aid sites was only 500, BBC Verify published an investigation examining several earlier incidents where Israel was accused of killing civilians seeking aid.
UK Foreign Secretary David Lammy will soon deliver a statement in the House of Commons on the situation in the Middle East.
It comes hours after a joint statement by the UK and 24 countries, calling for an end to the war in Gaza.
You can watch live at the top of this page and we'll bring you updates from Westminster as they happen.
Israel's foreign ministry spokesman Oren Marmorstein says the statement from 25 countries released earlier this afternoon, calling for the end of the war, is "disconnected from reality" and the Israeli government "rejects" it.
"The statement fails to focus the pressure on Hamas and fails to recognise Hamas’s role and responsibility for the situation," he writes on X, and says that Israel has agreed to a ceasefire proposal which Hamas "stubbornly refuses to accept".
"Hamas is the sole party responsible for the continuation of the war and the suffering on both sides. At these sensitive moments in the ongoing negotiations, it is better to avoid statements of this kind," he says.

There have in recent years been many international statements condemning Israel’s tactics in Gaza.
But this declaration is notable for its candour, reflecting both western frustration at Israeli intransigence and also the growing political pressure that many governments are feeling.
The signatories are largely European - plus Australia, Canada, New Zealand and Japan.
They nod to the most notable but unsurprising absentee, the United States, saying they support US efforts to find a ceasefire.
But they are brutal in their dismissal of the new US-supported mechanism of delivering aid in Gaza, which they condemn as the drip feeding of aid and the inhumane killing of civilians.
In a key paragraph, the 25 countries say they are prepared to take further action to support a ceasefire and political pathway to security and peace.
That is code for recognising a state of Palestine, something many countries have done but not all, including the UK and France.
That is one point of leverage on Israel that both countries are discussing but have yet to pull.
Responding to a BBC question about UN staff remaining in Deir al-Balah while the Israel Defense Forces (IDF) launches its assault on the city, the IDF says it is maintaining "ongoing and continuous contact" with international aid organisations working in the area, in order to help evacuate "essential institutions".
"This includes coordinating the relocation of vital centres to alternative locations based on the needs presented by these organisations," the statement says.
The IDF does not comment on the operation directly, but it does say it "will not refrain from operating in areas where terrorist activity that threatens Israel’s security is taking place".
Rachel Cummings, the humanitarian director for Save the Children has described to the BBC hearing the Israeli bombardment on Deir al-Balah.
Cummings tells BBC Radio 4's World at One programme she "can hear the military action from where we are. The bombardments, the drones, the artillery."
Deir al-Balah is where many humanitarian organisations are now based because the city, until today, had not been subject to Israeli army incursions and critical infrastructure like drinking water and medical points continued to function.
The situation in the Deir al-Balah, and across the whole of Gaza, "remains absolutely dire", she adds.
Cummings says yesterday's evacuation notice is the fourth in a week and 17th in the last month, pushing people further south.
The people of Gaza "are constantly forcibly displaced and nowhere is safe now in Gaza", she says.
Cummings says there is overcrowding in Deir al-Balah, as well as in Al Mawasi and Khan Younis, "where people are being pushed further into".

As we've been reporting this afternoon, the UK and more than 20 other nations have signed a joint statement calling for an end to the war in Gaza.
It's a long statement, so here are some of the main points from it summarised:
Image source, ReutersPope Leo warned against the "indiscriminate use of force" and the "forced transfer of the population" of Gaza in a phone conversation with Palestinian President Mahmoud Abbas on Monday, according to a statement from the Vatican.
The Pope also emphasised the urgent need to "provide assistance to those most vulnerable to the consequences of the conflict and to allow the adequate entry of humanitarian aid", the statement says.
Last week, Pope Leo renewed his call for a Gaza ceasefire after three people sheltering in the Catholic church in Gaza City were killed in an Israeli strike.
A telegram said the Pope was "deeply saddened to learn of the loss of life and injury caused by the military attack" on the Holy Family Church.

Compared to other areas in Gaza, Deir al-Balah had been spared from intense bombardment as it was the focus of relocated humanitarian efforts and where those still held captive by Hamas are assumed to be.
Following reports of evacuation orders, the families of the hostages taken on 7 October 2023 Hamas attacks said they were "shocked and alarmed".
In a statement the families say they demand that Prime Minister Benjamin Netanyahu, alongside his defence minister, chief of staff and spokesperson, "appear before them and the Israeli public this evening to clearly explain why the offensive in the Deir al-Balah area does not put the hostages at serious risk".
The families say they are yet to receive any official, organised updates, or "satisfactory answers" on the decision.
"The people of Israel will not forgive anyone who knowingly endangered the hostages—both the living and the deceased. No one will be able to claim they didn't know what was at stake," the statement adds.
Local doctors say several Palestinians have been killed in Israeli airstrikes in Deir al-Balah, our Middle East correspondent Yolande Knell reports.
