Earlier today, members of the Jewish community gathered in Trafalgar Square, London, to call for the safe return of hostages from Gaza.

Security was high, there was a significant police presence as well as representatives from the Community Security Trust charity.

The Israel national flag was visible across the event, as were photos of loved ones who have been taken hostage and remain missing. Their names were read out on the steps outside the National Gallery.

Later a minute's silence, and a group prayer, followed speeches from MPs and leaders of the Jewish community.

Let's return now to some of the people being held hostage by Hamas in Gaza - and their families who are desperate for them to be freed.

I've spoken to a British-Israeli woman who told me she is "worried sick" for her diabetic mother and brother - they're believed to have been taken from Israel.

Ayelet Svatitzky's mother Channah Peri, 79, and brother Nadav Popplewell, 51, were taken by Hamas when their kibbutz in southern Israel was attacked on 7 October. Her other brother Roi, 54, was killed.

On the day of the attack, Ayelet said she was sent two pictures by the attackers from her mother's phone, showing them sitting in her mother's living room. Underneath was written "Hamas" in English.

It's gone 22:00 in Israel, where the war with Hamas - which rules the Gaza Strip - has entered its third week. If you're just joining us, or need a catch up, here are some of the latest developments:

• Iran's foreign minster warned Israel and the US that the Middle East may "go out of control" if Israel military action continues - and blamed the US for providing military support to Israel
• Hours later, Israeli PM Benjamin Netanyahu warned troops his people were in a battle for their lives and said the war against Hamas is "do or die"
• US Secretary of State Antony Blinken responded to Iran with a warning against any "escalation" of the conflict
• The Al-Aqsa Martyrs hospital in central Gaza said it was running out of material to cover the dead with a day after Israel said it was intensifying air strikes
• Another convoy of trucks trying to get aid into Gaza has spent hours waiting at the Rafah crossing from Egypt - it's not clear when or if they'll get in today
• And a little earlier, the Israeli military admitted one of its tanks had accidentally fired on an Egyptian position near the border with Gaza. Egypt's military said there were "minor injuries"

We're hearing from the UN's agency for Palestinian refugees, which says 29 of its staff have now been killed since the war between Hamas and Israel broke out earlier this month.

The agency - known as UNRWA - described being "in shock and mourning". It had previously reported the deaths of 17 staff members.

"Half of these colleagues were teachers," the agency added of its latest toll.

Thousands of Gazans have sought shelter at UNRWA facilities since Israel launched retaliatory strikes on Hamas after the organisation carried out deadly attacks on Israeli military posts and kibbutzes on 7 October - killing more than 1,400 people and taking more than 200 hostages into Gaza.

The Hamas-run health ministry in Gaza says more than 4,600 have been killed there.

The crossing that connects Egypt to the southern Gaza Strip opened yesterday for the first time since the Israel-Hamas war erupted to allow 20 trucks to carry aid in. Two other border crossings from the strip go into Israel - both are shut.

Hamas and Egypt exercise control over who can pass through, but Egyptian media said the crossing was shut following three Israeli strikes on 9 and 10 October.

On 12 October, the Egyptian government asked Israel to halt strikes near the crossing but made it clear it would not reopen the passage without safety guarantees for staff and supplies.

On 20 October, around 175 trucks with life-saving aid waited on the Egyptian side for entry. On 21 October, the first 20 trucks crossed. Today, 17 more trucks were seen lining up.

Israel has refused to allow fuel to cross the border but aid leaders say fuel is essential to power water pumps, with water quickly running out in Gaza.

At the Rafah crossing today, more trucks were waiting to carry aid into the Gaza Strip.

Everything has to be checked - it takes time and the situation is tense.

This evening, the Israeli military admitted one of its tanks had accidentally fired on an Egyptian position near the border.

These first, tiny shipments of aid are making virtually no difference to the plight of more than two million Palestinians caught in an increasingly apocalyptic situation.

The UN says much, much more aid is needed, and it has to include fuel, which Israel has been blocking for more than two weeks.

Earlier we reported that the Israeli military said it had accidentally fired a tank and hit an Egyptian post near the border with Gaza, in Kerem Shalom.

Egypt's military has since said some of its guards on the border suffered "minor injuries", without offering further details.

The Israel Defense Forces released a statement after the incident saying the details were being investigated.

We reported earlier on the desperate scenes at a Gazan hospital - Al-Aqsa Martyrs - where a staff member said they were running out of material to cover the dead.

Images, some of which we decided not to share, showed bodies stacked in a courtyard outside. Inside doctors battled to patch up the walking wounded and save the gravely injured.

Similar scenes are being played out at hospitals across Gaza as the Israel-Hamas war stretches into its third week.

Earlier, we reported on a warning from Iran's foreign minister that the Middle East could spiral out of control if Israel's military action continues.

Now, US Secretary of State Antony Blinken has warned Iran against any "escalation" of the conflict. "We are concerned at the possibility of Iranian proxies escalating their attacks against our own personnel, our own people," he said on CBS News.

"We expect there is a likelihood of escalation," he added.

It's another reminder of the impact the conflict is having on the wider region.

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

Iran-backed Hezbollah has been designated a terrorist organisation by the UK, US and other countries.

Tensions are rising on Israel's northern border with Lebanon, and Israeli communities nearby are evacuating.

Netanyahu also called Israel's war with Gaza a "do or die" moment.

Israel’s Prime Minister Benjamin Netanyahu has, again, warned the powerful Lebanese group Hezbollah against joining the current conflict with Hamas, saying the response would be of an unimaginable magnitude.

Cross-border attacks between Iranian-backed Hezbollah - along with its allied Palestinian factions in southern Lebanon - and the Israeli army have escalated in recent days, and the question about what Hezbollah will do next hangs over Lebanon.

Residents are leaving border villages, and countries are warning against travel to Lebanon, with some telling their citizens to leave. So far, however, the violence has been contained.

Hezbollah - which fought a devastating month-long war against Israel in 2006 - has a vast arsenal of weapons, including guided missiles that can strike deep into Israeli territory, as well as tens of thousands of well-trained, battle-hardened fighters.

The group’s secretive nature means it is difficult to know what preparations it could be making. Its leader, Hassan Nasrallah, has remained silent since the Israel-Hamas war broke out. But a source close to Hezbollah told me he is monitoring the situation and has been in regular contact with the group’s military leaders.

Hezbollah, like Hamas, is considered a terrorist organisation by countries including the UK and the US.

The family of British teenager Noiya, 16, her 13-year-old sister Yahel and their mother Lianne have confirmed they were murdered in the attack on Kibbutz Be’eri.

Noiya had been missing since the massacre at the kibbutz on 7 October. The girls’ father Eli is still missing. Other relatives have been kidnapped.

Her British family told me this afternoon she had been formally identified - they said Noiya was "clever, sensitive, fun and full of life - her smile lit up the room like a beacon". They added:

After Yahel’s death was confirmed last week the family said she was "a bundle of energy" who loved "riding her bike at breakneck speed around the kibbutz, playing football, singing and dancing to TikTok and YouTube with sister, Noiya, and, on occasions her British cousins".

They said Lianne, the girls' mother, was the "light of our family's life" - and she had a "wonderful, caring nature". They added: "She would help anyone in trouble - be it physical, emotional or financial, she would be there for them. She was funny, with a dry sense of humour."

The family of a British teenager who was missing after Hamas's attack on Kibbutz Be’eri in southern Israel say she has been murdered.

The family of Noiya Sharabi,16, have told the BBC she has been formally identified.

Noiya's sister, 13-year-old Yahel, and their mother Lianne were also killed in the 7 October attack.

The Israeli military has just said that one of its tanks accidentally fired and hit an Egyptian post near the border with Gaza, in Kerem Shalom.

Kerem Shalom is a solely commercial goods junction in southern Gaza that is currently closed. It sits near the junction of Egypt, Gaza, and Israel.

The Israel Defense Forces expressed its "sorrow" following the incident and said the details were being investigated.

We'll bring you more when we hear it.

“We have never announced there is going to be a ground operation,” insisted Israeli Defence Forces spokesman, Lieutenant-Colonel Peter Lerner, to the World Service’s Newshour programme earlier.

As for the hundreds of thousands of IDF reservists along the Gaza border, Lerner said they were “currently being trained, equipped, and also tasked if they need to mobilise with specific tasks that will help us achieve our goal to destroy Hamas once and for all”.

In recent days, IDF spokesmen have emphasised the current focus is intensifying airstrikes before “the next stage of the war”.

There seemed to be the clearest signal yet yesterday from the IDF chief of staff Herzi Halevi: “We’ll enter Gaza, we’ll enter for an operational mission.” Observers say that could first involve limited raids.

Israel is coming under intense pressure from allies and Israeli families to delay a ground attack until hostages are freed, including foreign nationals.

It’s clearly a consideration, although Israeli officials also accuse Hamas of trying to buy time.

And there’s a chorus of voices urging Israel to allow more desperately needed aid to enter Gaza, even to agree a humanitarian ceasefire. That’s not on Israel’s agenda after the Hamas attacks of 7 October.

We're still waiting for an update from the Rafah crossing, where a convoy of trucks was seen approaching Gaza from Egypt.

Images show Egyptian Red Crescent members and volunteers gathering next to trucks carrying humanitarian aid - presumably water, food and medical supplies - as they drive into the crossing.

We've also been reporting that fuel trucks have been seen near the crossing. But there's still some confusion as to whether these trucks are entering Gaza.

Last week, trucks that were already inside Gaza headed towards the Rafah crossing to pick up fuel, which is stored nearby, and then went back into the enclave with supplies. A similar situation could be unfolding today.

We'll bring you more from the crossing as we hear it.

Earlier the UN warned that its fuel supplies in Gaza would only last for another three days.

We've just been sent this update from our correspondent Rushdi Abualouf, who is reporting from a camp in Gaza where about 2,000 displaced people are living in tents.

He says people in the camp, which was set up by the UN Relief and Works Agency for Palestine Refugees in the Near East, are struggling to find water, food, medication and bathrooms.

A little more now from Israeli Prime Minister Benjamin Netanyahu, who is visiting troops massing in the country's north.

He told them the country was facing a battle on two fronts: one to wipe out Hamas in Gaza, the other to "hold action" in the north, on Israel's border with Lebanon.

He said he could not say whether Hezbollah, Lebanon's most powerful military force, had decided to enter the war. If they did, he warned, Israel would strike them with a force they could not even imagine.

Netanyahu thanked the troops and acknowledged they had already lost friends. But he said this as a battle for life and home.

Skirmishes along Israel’s northern border have been escalating day by day and the authorities have already evacuated tens of thousands of civilians living near the border.

The war between Israel and Hamas has big implications for the wider region.

And today, Iran's foreign minster has warned Israel and the US that the Middle East may spiral out of control if Israel does not immediately stop its military action.

Speaking in Tehran, Hossein Amir-Abdollahian said: "I warn the US and its proxy (Israel)... that if they do not immediately stop the crime against humanity and genocide in Gaza, anything is possible at any moment and the region will go out of control."

Israel has been exchanging fire with the Iran-backed Hezbollah militia in southern Lebanon (earlier today, more Israeli communities near the border with Lebanon were ordered to evacuate).

The US, meanwhile, has sent an aircraft carrier to the region and a US destroyer in the Red Sea has intercepted missiles fired from Yemen by the Houthis, an Iran-aligned group. A base housing US forces in Iraq has also come under rocket and drone attack by Iran-backed groups.

Iran has denied helping Hamas carry out its 7 October attack on Israel, which killed 1,400 people. The US says it has not seen evidence of direct involvement by Iran.

We're still waiting to hear the status of aid trucks that have arrived at the crossing into Gaza from Egypt.

Fuel trucks appear to be moving inside the Rafah crossing, according to reports from the ground, but the UN says no fuel has yet been transferred.

While we wait for concrete details, here's why fuel is so important inside Gaza, where it is running low.

A UN report said that fuel is a necessity, and a lack of it is contributing to the water crisis in Gaza, as desalination plants and water pumps can no longer operate. It is also urgently needed to power generators in hospitals.

The International Committee of the Red Cross warned last week that hospitals in Gaza risked turning into morgues without electricity.

Medical centres have been overwhelmed since Israel imposed a "complete siege" on Gaza, pounding the territory with air and artillery strikes in response to Hamas gunmen infiltrating Israel and killing 1,400 people two weeks ago.

Israel had vowed not to restore electricity into Gaza until Hamas releases the more than 200 hostages it abducted during its attacks.

But yesterday, Israel allowed 20 trucks carrying aid to cross into Gaza after days of negotiations.

Once again, there have been a lot of developments in the Israel-Hamas conflict today. If you're just joining us, here are a few lines to catch you up.

Israeli airstrikes continue:

• The Hamas-run health ministry in Gaza says 266 Palestinians have been killed in the last 24 hours, including 117 children. This brings the total death toll to 4,651 since Israel began its offensive in the Gaza Strip, it says
• Overnight air strikes in Gaza have killed "dozens of terrorists", the Israeli military says, including a senior Hamas commander. Yesterday, it vowed to step up the intensity of its bombing, two weeks on from Hamas' initial attack that killed 1,400 Israelis

Hospitals in Gaza:

• We have seen graphic images showing the bodies of at least a dozen children at a hospital in central Gaza. We have decided not to show these images - 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
• The hospital says it is running out of shrouds for the bodies that are arriving at its doorstep

At the Lebanon-Israel border:

• Fourteen Israeli communities near the border with Lebanon have been ordered to evacuate, joining 28 others that were instructed to leave on Monday
• Israel's PM Benjamin Netanyahu has said Hezbollah - Lebanon's most powerful military force - would be making the "mistake of its life" if it enters the conflict

The West Bank:

• In the early hours of this morning, the Israeli military said it had attacked a terrorist compound in Jenin in the West Bank. It says a Hamas cell was stationed within a mosque
