The Israel Defences Forces (IDF) chief of staff has reminded troops they are "absolutely not" permitted - under the rules of engagement - to shoot unarmed people holding up a white flag in surrender.

General Herzi Halevi was speaking to troops in the wake of the accidental killing of three Israeli hostages in Gaza by soldiers on Friday.

He told soldiers to "take two seconds" if they see people "who do not threaten you, who don’t have weapons, who have their hands up".

Halevi stressed that even enemy fighters, if they put down their weapons and raise their hands, must be taken prisoner, not shot.

Three Israeli hostages - Yotam Haim, Samer Talalka, and Alon Shamriz - were shot dead after they emerged from a building shirtless, hands raised and with a white flag. Israel said they were mistaken for terrorists.

The Jabalia area, north of Gaza City, has been repeatedly hit by Israeli air strikes and has been a focus of the Israeli ground operation during the war, with the IDF saying it has been targeting terrorists and terrorist infrastructure there. A large number of buildings have been destroyed and entire streets reduced to rubble.

The largest of Gaza's eight Palestinian refugee camps is located in Jabalia. It is was set up after the 1948-49 Arab-Israeli war and is home to 116,000 refugees registered with the UN. The IDF considers the camp a stronghold of Hamas and it has been a focus of Israeli ground forces over the past few weeks.

The Hamas-run government said at least 195 people were killed in Israeli air strikes on Jabalia camp on 31 October and 1 November. The IDF said it had targeted and killed Hamas commanders there.

It's just gone 12:30 in Israel and Gaza now. Here’s a recap of what’s happened so far on day 73 of the Israel-Hamas war.

• Hamas officials have said that 110 Palestinians have been killed in Israeli airstrikes on the Jabalia refugee camp in northern Gaza.
• The Israeli military has not directly addressed the issue but says it is operating in the area
• US Defence Secretary Lloyd Austin has arrived in Israel to meet Israeli government officials – the Reuters news agency is reporting he is expected to discuss Israel’s planning for a transition to the next phase of war
• Meanwhile, the IDF has said it has found the biggest Hamas tunnel in Gaza so far, just 440m, (1,310 feet) from the Erez border crossing between Israel and the Gaza Strip

Witnesses and some local journalists say that at least four Israeli missiles struck three buildings inside the Jabalia refugee camp last night.

The Hamas-run health ministry in Gaza says 110 people were killed, and about 20 to 30 others are trapped beneath the remains of the three buildings.

Verifying information from northern Gaza is very difficult because of communication problems - there have been several communications blackouts since the war there started.

Jabalia is the biggest camp in the north of Gaza and the Israeli military has been operating in and around the camp over the past two weeks.

Some tanks have now moved out of the camp, but the air strikes intensified overnight.

US Defence Secretary Lloyd Austin has landed in Israel, as international pressure for a ceasefire in Gaza intensifies.

Austin is due to hold talks with his Israeli counterpart Yoav Gallant and Prime Minister Benjamin Netanyahu.

According to the Reuters news agency, a senior US defence official told reporters traveling with Austin that he was expected to discuss Israel's planning for a transition to the next phase of the war.

Over the weekend, France called for an "immediate and durable truce" in Gaza, while the UK and Germany have urged a "sustainable ceasefire".

The IDF has given an update on its "operational activity" in Jabalia, but hasn't given any details about the reported airstrikes in the area.

In a statement, it says that during the operation, the IDF found 5,000,000 Israeli new shekel (£1.1m) "designated for terrorist activity inside a senior Hamas terrorist’s residence".

It also says it "struck terrorist infrastructure" where weapons were located, including explosive devices and military equipment, adding that its forces destroyed "terror tunnel shafts".

A brief update was also given on the situation in Khan Younis in the south of Gaza, with the Israeli military saying it has eliminated a “suspicious terrorist cell” there as well as undertaking other operations from the air and sea.

Hamas officials say that the death toll following airstrikes in Jabalia, northern Gaza, has risen to 110.

We're still working to establish the details. In the meantime, here's a look at everything we know so far:

• Strikes hit a residential block on Sunday, leaving many killed and at least 50 people buried under rubble, Hamas officials in Gaza say
• The Israeli military has not directly addressed what happened but has said it is operating in the area, targeting what it calls terrorist infrastructure

• A journalist in the area said that civilians were rescuing those still under the rubble, with Palestinian civil defence unable to gain access

Over the weekend three of Israel's allies called for the fighting in Gaza to end.

UK Foreign Secretary David Cameron teamed up with Germany's Foreign Minister Annalena Baerbock to call for a ceasefire of the Israel-Gaza war - but only if it's "sustainable".

Cameron and Baerbock jointly wrote an article for the UK's Sunday Times, saying: "Our goal cannot simply be an end to fighting today. It must be peace lasting for days, years, generations."

The UK and Germany had earlier last week abstained over a United Nations resolution, backed by 153 countries, demanding an immediate humanitarian ceasefire in Gaza.

French Foreign Minister Catherine Colonna said "too many civilians are being killed".

Last night Israeli airstrikes reportedly targeted a block in Jabalia refugee camp in the north, where three families were living. Local journalists and the Hamas-run Gaza health ministry said that 90 people have been killed and 50 people are still under the rubble.

Since the Palestinian civil defence is not able to reach the area, civilians are trying to rescue them, according to a journalist in the area.

Israeli forces have been targeting Jabalia for two weeks, tanks were surrounding the camp from many directions.

The airstrikes intensified in the area last night. I have seen some photos showing many bodies of children and women around a medical facility in northern Gaza. They were reportedly killed by an Israeli airstrike elsewhere in the north of the Strip.

The UN Security Council could vote later on a proposal to demand that Israel and Hamas allow aid access to Gaza via land, sea and air routes.

The AFP news agency reports there is new resolution planned for today, drawn up by the United Arab Emirates, calling for an "urgent and sustainable cessation of hostilities" in Gaza.

The new resolution also calls for the immediate and unconditional release of all hostages and affirms support for a two-state solution.

The US blocked a previous security council resolution calling for a "humanitarian ceasefire".

Lloyd Austin is expected to arrive in Israel today to meet with the country’s leadership as international pressure mounts over the civilian death toll in Gaza.

The US defence secretary's trip will form part of efforts to encourage Israel to transition away from major combat operations in Gaza and to a more limited campaign against Hamas, the Associated Press reports.

Austin is expected to travel on to Qatar and Bahrain for talks on improving security for commercial shipping in the Red Sea.

On Sunday, he was in Kuwait to offer condolences on the death of the country’s emir, Sheikh Nawaf al-Ahmad al-Sabah, the previous day.

Former UK defence minister Ben Wallace warns in the Daily Telegraph, external today that Israel's tactics in Gaza will "fuel the conflict for another 50 years" and risk radicalising Muslim youth across the globe.

Wallace says he is not calling for a ceasefire. "You can’t have a ceasefire with Hamas unless they are prepared to declare one," he says. But he adds Israel needs to "stop this crude and indiscriminate method of attack".

“Going after Hamas is legitimate," Wallace writes. But "obliterating vast swathes of Gaza is not."

"I am unequivocal in my condemnation of Hamas, he says, adding they are "using Palestinians as cannon fodder".

"[Hamas] is anti-Semitic and anti-democratic. It isn’t interested in peaceful co-existence with Israel."

But this generation of Israel politicians, says Wallace, is acting "like a bull in a China shop".

Fierce fighting has been continuing across the Gaza Strip after hopes were raised over the weekend for another ceasefire and hostage release deal.

In the past day, there’ve been deadly Israeli air strikes from the north to the south of Gaza. Attacks on the Jabalia refugee camp are said to have killed 90 people, according to local health officials.

Israel says it goes to great lengths to avoid hitting civilians. But the mistaken killing of three of its own hostages carrying a white flag on Friday has added to international and domestic pressure for another ceasefire deal which could free some of the 120 others still believed to be held captive in Gaza by Hamas.

Israel is also expected to face pressure to scale back its major combat operations when US Secretary of Defense Lloyd Austin visits later.

At the UN Security Council, the US is said to be seeking to tone down the words of a new draft resolution calling for a cessation of hostilities to allow greater humanitarian access.

In response to calls from Washington, Israel has now opened its Kerem Shalom crossing into Gaza for the first time since the outbreak of the war, in a move intended to increase the amount of food and medicine reaching Gazans.

Hamas health officials say at least 90 Palestinians have been killed in Israeli airstrikes on the Jabalia refugee camp in Gaza. The strikes hit a residential block housing two families, the health ministry said.

The BBC was unable to confirm the toll.

There's been no immediate comment from Israel, which insists it is targeting what it called terrorist infrastructure.

The Israeli army says it has found the biggest Hamas tunnel in Gaza so far, only 400m (1,310 feet) from the Erez border crossing between northern Gaza and Israel.

An AFP photographer was granted access to the tunnel and said it was big enough to fit a vehicle through it.

The Israeli military claims the tunnel would have cost millions of dollars and taken years to construct. It said the tunnel system had branches that together covered more than 4km (2.5 miles).

It claimed that the tunnel's construction was overseen by Mohamed Yahya, brother of senior Hamas commander Yahya Sinwar who is believed to have orchestrated the 7 October attacks.

The Israeli Defense Force (IDF) also said it had found a large number of weapons stored in the tunnel.

An Israeli army spokesman, Lieutenant Colonel Richard Hecht, says Hamas expended huge resources on the project to "serve only one purpose, attacking the state of Israel and its residents".

The BBC has not verified the claims.

The BBC has previously verified drone footage released by Hamas in October showing Israeli troops near a tunnel close to Erez. The IDF posted on its Telegram account in October that "soldiers operating adjacent to the Erez Crossing identified a number of terrorists exiting the shaft of a tunnel".

Satellite images appear to show excavation work in the area in late November.

It's a very explicit call from David Cameron and Annalena Baerbock, both writing in major newspapers to call for a ceasefire.

France’s Foreign Minister, who visited Israel yesterday, has also called for an immediate ceasefire.

This is slightly semantics about what is the difference between an immediate ceasefire and sustainable ceasefire.

But the fact is that I don't think any of Israel's allies, which include Britain, the US and Germany, envisaged this when on 7 October they pledged their full support for Israel and its right to defend itself.

I don't think any of them envisaged a death toll of approaching 20,000 people in Gaza.

So there is a real momentum internationally to curtail Israel's military operation. Not to stop it all together but at least to reduce the amount of suffering and deaths on the part of the Palestinians.

There are also questions being asked internationally about the discipline and rules of engagement of the Israeli forces.

Over the weekend three of Israel's allies called for the fighting in Gaza to end.

UK Foreign Secretary David Cameron teamed up with Germany's Foreign Minister Annalena Baerbock to call for a ceasefire of the Israel-Gaza war - but only if it's "sustainable".

Cameron and Baerbock jointly wrote an article for the UK's Sunday Times, saying: "Our goal cannot simply be an end to fighting today. It must be peace lasting for days, years, generations."

The UK and Germany had earlier last week abstained over a United Nations resolution, backed by 153 countries, demanding an immediate humanitarian ceasefire in Gaza.

French Foreign Minister Catherine Colonna said "too many civilians are being killed".

Vehicles from Egypt carrying aid through the city of Rafah into Gaza have been mobbed by crowds of people trying to get hold of vital supplies.

In footage obtained by the Associated Press, a lorry can be seen swerving, causing aid boxes to come crashing down from the back.

In other pictures, dozens of people scrambled to salvage scattered aid boxes lining the middle of the road.

It's just ticked over 07:15 in Gaza and Israel, and 05:15 in London - if you’re just joining us, here’s a quick catch-up on the latest developments.

UN aid has entered Gaza directly from Israel for the first time since fighting broke out, but humanitarian workers say it's getting increasingly difficult to distribute supplies in the territory. Over the weekend desperate crowds were filmed chasing aid trucks near Rafah, and stripping them of food and water.

The Hamas-run Gaza health ministry says Israeli air strikes have killed at least 90 people in the Jabalia refugee camp. The BBC has been unable to confirm the toll.

Israeli PM Benjamin Netanyahu has again rejected calls for a ceasefire as pressure on his government mounts both at home and abroad. Over the weekend large crowds rallied in Tel Aviv calling for a new hostage deal, and the UK, Germany and France all called for the fighting in Gaza to stop.

Today we're expecting another visit to Israel from a top US official - this time, US Defence Secretary Lloyd Austin. The US has been growing increasingly critical of Israel's military operation in Gaza, and Austin has previously said the impact on civilians means Israel risks replacing "a tactical victory with a strategic defeat".
