But the BBC understands photographer Dan Darlington is believed by his family to be dead.

The US government has confirmed nine of its citizens have been killed in Israel.

In a statement, the White House said: "We extend our deepest condolences to the victims and to the families of all those affected, and wish those injured a speedy recovery.

"We continue to monitor the situation closely and remain in touch with our Israeli partners, particularly the local authorities."

A 22-year-old Irish-Israeli woman is among those missing after Hamas gunmen attacked the Supernova music festival near the Gaza border in a murderous rampage, leaving nearly 300 people dead.

In an interview with ABC News, Jennifer Damti said her daughter, Kim, had phoned them shortly after the attack began.

“Kim didn’t realise there was like seven or eight Toyota vans full of terrorists and they just shot everywhere," she said.

Irish Taoiseach (prime minister) Leo Varadkar said the government was aware of the case, and consular officials were in touch with the family.

UK Prime Minister Rishi Sunak will host a Cobra emergency meeting later on Monday amid the ongoing violence in Israel and Gaza following the attack by Hamas.

Speaking at an event in Nottinghamshire, Sunak said the scenes coming from Israel were "horrifying" and Hamas were committing acts of terrorism.

Sunak said he was working "very closely" with Israel to help any British nationals in the country.

He added that he would provide any support needed to Israel, whom he called a strong ally.

The UK Foreign Office has advised against all but essential travel to the region.

Air raid alerts have sounded in northern Israel, with reports of rockets being intercepted from Lebanon by Israel's air defence.

On Sunday, the Islamist militant group Hezbollah fired missiles and artillery shells into Israel from southern Lebanon "in solidarity" with Hamas.

No one was reported hurt. Israel responded by firing into the area of where the cross-border fire was launched from.

UK chief rabbi Sir Ephraim Mirvis has told the BBC "there is hardly a Jewish family in the UK which is not affected in one way or another by what has happened in Israel".

He said this was a "time of mourning, of deep grief, and of enormous worry" for the Jewish community.

He also warned that "all steps need to be taken in order to guarantee safety".

On Monday, a Kosher restaurant in Golders Green, north London, was vandalised and a bridge metres away graffitied with "Free Palestine".

The Metropolitan Police said no arrests had been made, and the incident was not being treated as a hate crime.

On Sunday, the police said they were boosting patrols in parts of London to provide "visible presence and reassurance to our communities".

A man who believes his mother was kidnapped from a kibbutz in Israel, 400 metres from Gaza, has told the BBC he learned something was wrong when he saw Palestinian media broadcasting from her front lawn.

Speaking on Woman's Hour, Noam Sagi said the Israeli army went into his mother Ada's home and found blood stains.

He said the grandmother-of-six is not listed on either the official dead or missing list. But he said at least 20 - mostly elderly people and young children - were also abducted from the community of around 350 people.

Ada recently had a hip replacement and needs an epi-pen for severe allergies, Noam said, adding he is very scared for her wellbeing.

Describing the situation as "like a horror film", Noam said: "It is very upsetting to even think that this is possible.

Two refugee camps have been hit by Israeli air strikes in Gaza, according to the Palestinian Ministry of Foreign Affairs.

It says both the Al-Shati (also known as the Beach camp) and Jabalia camps were attacked, reportedly leaving several injured and dead.

There are eight recognised refugee camps, external in the densely-populated Gaza Strip.

Gaza's health ministry says 511 people have been killed, and 2,750 injured, as a result of Israeli missile strikes on the Gaza Strip since Saturday.

Israel says it is striking Hamas targets in Gaza following Saturday's unprecedented assault on Israeli civlians and soliders by Palestinian gunmen who entered from the enclave, opening fire in the streets and in communities.

The Israeli military has just said it has launched an "extensive" attack on Hamas centres in Gaza.

Both the Israel Defence Force and Israeli Air Force announced the operation on social media.

It comes as Hamas resumes a large-scale rocket attack on Israel from the Gaza Strip.

Israeli air strikes overnight and this morning in Gaza killed four hostages, and the Hamas militants holding them, a spokesman for the militant group has said.

It is not known exactly how many people are being held captive by Hamas, having been kidnapped in Israel, but the Israeli military this morning said it was "dozens".

Reporting from Ashkelon

We were just wrapping up an interview in the southern Israeli city of Ashkelon when a missile siren sounded and we had to run for cover.

After waiting for the danger to pass, we headed to a building a few minutes away that was hit.

A couple with their two young children said they had to run for the shelter: “If we hadn’t made it in 20 seconds we would have been hurt. Our home is full of glass.”

We're getting updates on the waves of rockets being fired on Israel from Gaza.

In Ashkelon, just north of Gaza, four people have been wounded - one seriously - and taken to hospital for treatment, Israel's emergency services say.

In nearby Ashdod, a woman has been critically injured and also been taken to hospital.

Reporting from southern Israel, near Gaza

We saw dead bodies of Hamas fighters still lying on the ground - left to rot - unlike their Israeli victims who’ve long ago been taken away for identification and burial.

We watched as one Israeli driver stopped his truck so he could pick up a rock to throw at the corpse of one dead Hamas fighter. Anger erupted on both sides of the border.

While Israel’s well equipped and trained troops tries to eradicate the remnants of those militants who carried out the raid, Hamas continues to fire scores of rockets over the border - by day and night.

Israel’s sophisticated air defences - the so called Iron Dome - has been working overtime. It’s unable to intercept every rocket fired from Gaza.

The clear up operation at times sounds more like a full scale military operation - with Israeli jets constantly flying overhead and striking hundreds of targets inside Gaza.

But Israel is clearly planning much more. Tanks, troops and armoured vehicles are massing near Gaza’s border. It looks like preparations for a potential major military operation into Gaza itself.

Israel's Defence Minister Yoav Gallant says he has ordered a "complete siege" on the Gaza Strip: "No electricity, no food, no fuel."

As a reminder - Israel controls the air space over Gaza and its shoreline, and restricts who and what goods are allowed in and out through its border crossings.

Similarly, Egypt controls who passes in and out of its border with Gaza.

The Israel Defense Forces says air raid sirens are now sounding in Jerusalem and across Israel, as rockets are fired from Gaza.

At least three explosions have been heard in Jerusalem.

It is not yet clear if these are rockets landing, or being intercepted by Israeli defence.

Israel Defense Forces spokesman Daniel Hagari says the military has regained control of all communities near the Gaza barrier - but isolated clashes are ongoing with active Palestinian gunmen.

Earlier, the military said fighting was taking place in "seven or eight" places inside Israeli territory.

As we just reported, other countries are trying to get their citizens out of Israel.

At the same time, Israel's foreign minister says , externalspecial flights are being arranged to help Israeli military reservists living abroad get back to the country.

Eli Cohen says there have been "many requests" from Israelis around the world to return as soon as possible "to volunteer, to lend a hand".

Some military service is mandatory for most Israeli citizens, external, even if they are of dual nationality.

The IDF says it has recruited 300,000 reservists since Saturday - its highest mobilisation ever.

As the fighting continues in Gaza and Israel, countries are trying to get their nationals out.

A plane from Tel Aviv to Serbia landed today, and the Serbian Embassy says another flight is scheduled.

Romania's Minister of Foreign Affairs said around 800 people had been bought home from Israel, with more to come.

Thailand's government said they are preparing emergency teams and planes to rescue nationals in Israel.

Flights from Kazakhstan are also being readied, according to its foreign ministry.

This morning Poland confirmed the first plane had landed back in the country from Israel with civilians on board.
