Let's return to the Rafah crossing now, on the border of Gaza and Egypt.

The UN says 17 trucks, presumably carrying food, water and medical supplies - like the 20 trucks that went in yesterday - have arrived at the crossing and are currently being checked, but have yet to enter Gaza.

Live pictures a short time ago appeared to show fuel trucks among those moving inside the crossing.

However, the UN is saying that, as of yet, no fuel has reached Gaza.

Officials at UNRWA, the UN agency responsible for Palestinian refugees, say that no fuel has entered the Gaza Strip in more than two weeks - hospitals are among those that have been struggling.

"Without fuel, there will be no water, no functioning hospitals and bakeries,” a spokesperson said. “Without fuel, aid will not reach many civilians in desperate need. Without fuel, there will be no humanitarian assistance.”

We'll bring you more on the situation at the crossing as we get it.

Israel's Prime Minister Benjamin Netanyahu has warned Hezbollah - Lebanon's most powerful military force - against opening a second war front with Israel.

It would be making the "mistake of its life" if it did, he said when speaking to Israeli troops near the border with Lebanon.

He said it would bring Israeli counter-strikes of "unimaginable" magnitude that would wreak "devastation" upon Lebanon.

Israel and the US have already warned Iran-backed Hezbollah - which has been designated a terrorist organisation by the UK, US and other countries - against opening another battle front on Israel's northern border.

BBC Arabic's Adnan Elbursh has been reporting from Al Aqsa Martyrs hospital in Deir Al Balah in central Gaza, which has been overwhelmed with casualties.

Our reporter says procedures taking place at the hospital are extremely rushed, and bodies are being wrapped in white cloth in the outer courtyard.

We brought you photos from outside the hospital earlier - and this morning, we reported on images that were emerging of dead children at the hospital, including two babies.

Staff say the hospital is struggling to cope.

"We’ve been here since the crack of dawn and the bodies have completely filled the hospital yard, on top of the bodies which are in refrigerators which are full, inside the hospital building and outside," a member of staff says.

"We don’t have enough shrouds for the bodies because the numbers are huge. All bodies are arriving in parts, unattached and in pieces. We can’t identify them because the bodies have been disfigured and crushed."

In footage from the scene, a stream of vehicles is arriving carrying wounded people, some able to walk into the hospital.

A car arrives, tyres screeching and a man calls out: "Quickly, quickly!" The patient is rushed away. Inside, parents are carrying their wounded children.

"Frankly, the situation is catastrophic, it’s unbearable," says the member of staff.

"Despite everything we’ve witnessed before, these are scenes we’ve never seen."

In the past half hour, we've been seeing reports from news agencies and Egyptian media that 17 trucks carrying aid have arrived at the Rafah crossing between Egypt and the southern Gaza Strip.

Live footage from the border shows trucks and a UN vehicle lined up, but it is unclear if they have crossed into Gaza as yet.

The first convoy of 20 trucks carrying medical aid, food and water passed through the Rafah crossing yesterday.

The UN says Gaza is "on the abyss" and that about 100 trucks a day are needed to get sufficient supplies into the enclave.

Gaza's Hamas-run health ministry says at least 4,651 people have been killed in the Strip since 7 October.

It adds that 14,245 people have been wounded.

The ministry also says in a statement that 266 Palestinians have been killed in the past 24 hours, including 117 children.

We reported earlier on photos showing the bodies of dead children at Al Aqsa hospital in central Gaza. We wrote that images showed the bodies of 11 children and two babies. We have now seen another image, from the same photographer working for the AFP news agency, that shows the body of a 12th child.

Once again, we are deciding not to show this image. We want to reflect the gravity of this conflict, and its toll on civilians, while being sensitive about what you, the audience, is exposed to.

However, there are other images taken at the hospital that we can show, which you can view below. One of them shows what appears to be a child wrapped in a shroud, carried by a man. The body inside the shroud is not visible.

As with the photos of the children, we do not know when or where people in these photos died. The hospital is in the small city of Deir Al Balah, which has been hit by Israeli strikes over the past week. The city is outside the northern Gaza evacuation zone that Israel has told civilians to leave and flee south - it continues to bomb central and southern Gaza.

We're working to get more information from hospitals across Gaza.

Hanan Ashrawi, a veteran Palestinian politician, has accused the international community of double standards when it comes to Israel.

Speaking to Victoria Derbyshire this morning on the Sunday with Laura Kuenssberg programme, Ashrawi said Palestinians have been dying for decades.

Gaza is an area where "people haven't had a day of normal life," she continued, "and then when they lash out, when they break out, immediately all sorts of horrific labels are used".

Derbyshire then clarified whether Ashrawi's comments meant she thought Israeli citizens were legitimate targets, to which Ashrawi replied: "No, I don't believe in civilians being legitimate targets at all, in the same way that we are not legitimate targets of Israel: Our homes, our lands are not at its disposal, our freedom, our rights have been denied."

"What I am talking about is the double standard," she said. "Israel is an occupying power, this has to be acknowledged."

In our previous post, we reported on the Israeli air strike overnight in Jenin in the West Bank.

In case you need a reminder, the West Bank is an area of land located - as the name suggests - on the west bank of the River Jordan and bounded by Israel to the north, west and south. To its east lies Jordan.

It has been occupied by Israel since the 1967 Middle East war, but decades of difficult on-off talks between Israel and the Palestinians - both of whom assert rights there - have left its final status unresolved.

Between 2.1 million and 3 million (sources vary) Palestinian Arabs live in the West Bank under both limited self-rule and Israeli military rule.

The West Bank (excluding East Jerusalem) is also home to some 430,000 Israeli Jews who live in more than 130 settlements built under Israel's occupation.

As we reported earlier, the Israeli military said overnight it had attacked a "terrorist compound" in Jenin in the West Bank, which allegedly included a Hamas cell beneath a mosque.

The footage below from inside the mosque shows the building reduced to rubble after the strike.

We've been seeing a lot of very graphic images coming out of Gaza this morning, some of them showing the bodies of dead children at a hospital in central Gaza.

The images from the Al Aqsa hospital show the bodies of at least 11 children - including two babies - and many other dead Palestinians being wrapped in shrouds. The images come from a photographer working for the AFP news agency.

Many of them are too graphic for us to show here. When we report on this conflict, we have to decide what is appropriate to show you. We want to reflect the gravity of this war, and its toll on civilians, while being sensitive about what you, the audience, is exposed to.

One of the images shows dead children lying beside one another on a sheet, some with visible head injuries. Another image shows a child in the arms of a man - both are dead and the man has a clear facial injury.

It is not clear from the photos when or where the people died.

The hospital is in the small city of Deir Al Balah, which has been hit by Israeli strikes over the past week. The city is outside the northern Gaza evacuation zone that Israel has told civilians to leave and flee south. Israel has continued to bomb central and southern Gaza.

We're working today to find out more about what is happening at this hospital - and at others across Gaza.

Naftali Bennett, former Prime Minister of Israel, says the humanitarian crisis in Gaza is "none of our business".

Israel controls the air space over Gaza and its shoreline, and strictly controls the movement of people and goods.

"The world can come and help the Gazans, that's none of our business," he told Victoria Derbyshire during the Sunday with Laura Kuenssberg programme, when asked if Israel will allow more aid into Gaza.

He says humanitarian action must be reciprocal, citing hostages being held by Hamas.

Derbyshire puts it to Bennett it is Israel's business as it must demonstrate its fight is with Hamas rather than the Palestinian people.

"We are not responsible for Gaza like you are not responsible for France," he responded.

"If others want to take care of the Gazans, that's theirs to do."

Pressed further that Israel does control Gaza's borders, Bennett said Israel's notice to Gazans to move to the south was evidence of humanitarian action.

Images coming to us today from Gaza show the impact the ongoing conflict is having, with buildings destroyed and people looking for survivors in the rubble as Israeli airstrikes continue.

There have also been queues outside bakeries as people wait to buy bread amid shortages of food supplies and fuel.

Take a look at some of the latest photos:

More now from the update by the Israeli military, which has said it believes 212 people are being held hostage by Hamas in Gaza, up from its estimate of 210 yesterday.

On Friday, two American hostages - mother and daughter Judith and Natalie Raanan - were the first to have been freed.

We're keeping a close eye on any updates about those being held - including the people confirmed by the BBC, or credibly reported, to have been abducted by Hamas from Israel.

The Israeli military says overnight air strikes on Gaza have killed a senior Hamas commander.

A spokesman for the Israel Defense Forces, Daniel Hagari, said the deputy commander of Hamas's rocket force was killed alongside "dozens of terrorists", according to comments carried by the Reuters news agency and Israeli media.

Hamas is officially designated a terrorist organisation by the UK, US, and other countries.

A little earlier, Hamas, which has ruled Gaza since 2007, said 55 people were killed in overnight strikes. Images have shown the aftermath of air strikes in both central Gaza and in the south, in Rafah, which is close to the border with Egypt.

Israel is repeating its warning to civilians in the north to head south - parts of northern Gaza have been almost entirely flattened. Gaza is a relatively small area - the length of the strip is similar to that of London - and very densely populated.

Hagari said that Israel was ramping up its attacks on Gaza "in preparation for the next phase of the war" - which is expected to be a ground offensive. “We will go to the next stage under the best conditions for the IDF [Israeli military]," he said.

The Palestinian Red Crescent says fuel must be included in humanitarian aid allowed into Gaza if hospitals are to continue operating.

Speaking to BBC Radio's 5 Live, the organisation's Nebal Fasakh says: "This humanitarian aid doesn’t contain fuel which is vital for hospitals to keep running."

"Hospitals will shut down if we run out of fuel," they say, describing the situation in Gaza as "heart-breaking".

Yesterday's aid delivery - the first to enter Gaza since the war erupted - included medicines, food, water and coffins, but Israel has refused to allow fuel to cross the border.

As Israel's war with Hamas intensifies, tensions are also rising on the country's northern border with Lebanon.

Over the past few weeks, missiles from Lebanon have hit villages in Israel, and Israel's military has warned the Hezbollah militant group - Lebanon's most powerful military force - that it's playing a "very dangerous game".

Hezbollah, like Hamas, has been designated a terrorist organisation by the UK, US and other countries.

Now, Israeli residents living in 14 communities close to the Lebanese border are being evacuated, a joint statement between Israel's Ministry of Defence and its military says.

The 14 communities are Snir, Dan, Beit Hillel, She'ar Yashuv, Hagoshrim, Liman, Matzuva, Eylon, Goren, Gornot HaGalil, Even Menachem, Sasa, Tziv'on and Ramot Naftali.

They join 28 communities that were evacuated on Monday to "reduce harm to civilians" and to give the Israeli military "freedom of action if it is required".

The residents of the evacuated communities are living in state-funded guest houses.

Syrian state media is reporting that Israeli missile attacks have targeted the country's two main airports.

The Syrian Arab News Agency says the international airports of Damascus and Aleppo were attacked.

At least two civilian workers were killed at Damascus airport, Reuters reported, citing the Syrian government's general directorate of meteorology.

Syria's Damascus and Aleppo airports not only handle civil aviation but also host military bases, which are reportedly transit points for Iranian arms sent to Hezbollah - a militant group which is powerful in both Syria and Lebanon.

At both airports, the runways were damaged, putting them out of service, according to the state media report.

Both airports were also struck by Israel last week.

The International Committee of the Red Cross (ICRC) says as well as humanitarian supplies needed in Gaza, medical personnel also need to be allowed in to alleviate pressure on hospitals.

"What is most needed right now is a continued flow of humanitarian supplies and aid into Gaza," the ICRC's Sarah Davies told BBC Breakfast.

She says it's not just supplies themselves that are needed, "but medical personnel and surgical teams who can start to alleviate some of the pressure".

The border crossing between Egypt and Gaza was opened yesterday to allow 20 trucks of aid through - as agreed by Israel - but Davies said a continued flow of aid is needed.

"This needs to be sustained, people cannot survive with 20 trucks of aid, it really is such a dire situation," she said.

"We are in regular contact with our teams on the ground and the scenes they describe are horrific."

Hamas says at least 55 people have been killed in overnight air raids in Gaza, according to the news agency AFP.

It said more than 30 homes were destroyed in the hours after an Israeli military spokesperson said airstrikes on the Gaza Strip would intensify as its troops prepare for an anticipated ground offensive.

An Israeli military spokesperson, Daniel Hagari, said the attacks would help reduce risks for Israeli forces, who are massed around the border. He told Palestinian civilians in Gaza to keep moving south for their own safety, particularly those living in Gaza City.

Separately, Israel has carried out more deadly airstrikes in the occupied West Bank. The latest hit a mosque in Jenin, which the army described as a command centre for terrorists.

UK Prime Minister Rishi Sunak says the government is "working intensively with international partners" to allow trapped British nationals to use the Rafah crossing to leave Gaza.

Writing in the Sunday Telegraph, he welcomes the reopening of the Egypt-Gaza crossing - the only viable way out of Gaza - and says there needs to be a "stream of trucks rolling through" to bring aid.

And he says "all water supplies" need to be restored to Gaza "where physically possible". Water is scarce, and the World Health Organization estimates the average daily water consumption in Gaza is just three litres per person - the minimum daily requirement for basic needs is 100 litres.

Sunak also described meeting the families of British victims of the attacks by Hamas and the importance of reaffirming support for a two-state solution.

He said it was a "moment for care and caution - but also for moral clarity" and a "moment for humanity to win out against the scourge of terrorism".
