A US billionaire has donated $99,999 (US$ 65,000; £49,000) to a "hero" who tackled one of the Bondi Beach gunmen and wrestled his weapon off him (the maximum online donation is $99,999).

Video footage shows the 43-year-old fruit shop owner running towards the gunman and seizing the weapon. He then turns the gun on attacker forcing him to retreat.

A fundraiser created to raise funds for Ahmed Al Ahmed has raised close to $1million, according to GoFundMe.

The top donation is from William Ackman, the CEO of Pershing Square Capital Management, who has praised the "brave hero" for saving lives on X.

Ahmed's parents earlier said he was shot four or five times in the shoulder and is in hospital.

Minutes before 18:47 local time, the time of the attack yesterday, a group of Jewish people set up a large menorah by the bouquets on Bondi Beach and placed candles.

They announced they would light candles tonight - a ritual associated with the Jewish festival Hanukkah - to remember those killed in the attack.

"We invite people to take the light, to spread peace and tolerance. We have survived for thousands of years...light will always prevail," says one of the men.

Then the group led the crowd in the spontaneous singing of several traditional Jewish songs.

As their voices soared, some in the crowd sobbed as they sang and clapped along.

Then they continued with the Australian anthem, before singing more Jewish songs.

The two gunmen involved in yesterday’s shooting have been named by local media as 50-year-old Sajid Akram, who died at the scene, and his 24-year-old son Naveed Akram - who remains in hospital in a critical condition.

Here’s what we know about the attackers so far:

• Sajid Akram arrived in Australia on a student visa in 1998, which was transferred in 2001 to a partner visa and later resident return visas
• He had a firearms licence for recreational hunting and was a member of a gun club
• Naveed Akram first came to authorities’ attention in October 2019 but Australian Prime Minister Anthony Albanese said an "assessment was made that there was no indication of any ongoing threat or threat of him engaging in violence"
• The Australian broadcaster ABC reports Naveed Akram, who is an Australian-born citizen, was examined over his close ties to a Sydney-based Islamic State (IS) terrorism cell
• ABC also reports that counter terrorism police believe the gunmen had pledged allegiance to the IS terrorist group
• Police believe the gunmen had prepared for the attack at a short-term rental property around a 30-minute drive from Bondi Beach. A single-storey grey building in Campsie has become one of the main focuses of the police investigation
• Officers raided the gunmen’s family home last night, around an hour's drive away. One of their former neighbours told the BBC that when she saw the news of the shooting, "I thought oh my goodness, it can't be them"

Chief Rabbi Sir Ephraim Mirvis says his cousin and his cousin's wife spent "15 terrifying minutes hiding under a doughnut stand as terrorists were shooting at them and those around them" on Bondi Beach.

"Once again, Jews were targeted for the simple act of gathering together, visibly and peacefully, as Jews," he says in his Thought for the Day on BBC Radio 4.

"On Hanukkah, Jews around the world declare: we are here, we belong, and we will not hide who we are."

This period in the aftermath of the shooting "demands moral clarity", he says.

"Jews have lived with security concerns for as long as I can remember, but the fact that today every public Jewish gathering must be weighed for risk is a sign of something deeply wrong.

"A society in which a minority must calculate whether it is safe to be seen together in public, is a society that is failing all of its citizens."

We earlier reported details of some of the 15 people killed in the Bondi Beach shooting.

Since then, another victim has been named in local media as Tibor Weitzen.

He's a grandfather believed to be in his 70s and a member of the Bondi Chabad Synagogue, the Sydney Morning Herald reports.

Col Live, a Chabad news outlet, reports that he went to the Hanukkah event with his wife and grandchildren, and died trying to shield a family friend.

That family friend is also among the dead, according to the outlet.

As we've been reporting, 15 people were killed in yesterday's attack - among them a 10-year-old girl who has been identified in local media as Matilda.

Matilda's aunt Lina has spoken to ABC News, external about her niece.

"Matilda was very friendly, she loves school, and has a lot of friends," she says.

"She's just a happy kid, always gives me cuddles."

She adds that Matilda had been taken to the Sydney Children's Hospital at Randwick but had lost a lot of blood and could not be saved.

Lina also said Matilda's younger sister was present when her sister was injured but is physically unharmed.

"She's in absolute shock and stress, she's missing her sister badly," Lina said.

We are just coming up to 18:47 here in Bondi - the time of the attack yesterday - and a sizeable crowd of several hundred has grown at the Bondi Pavilion, the local landmark building at the beach.

Many are wearing black, while some openly weep.

Israeli and Australian flags have been hung up on the closed gates to the pavilion, as people come forward to lay wreaths and bouquets of flowers.

Some have also laid pebbles from the beach and candles.

The pile of bouquets is now enormous, and at the centre is a handwritten sign saying: "We stand united, no more hate, more love", ending with a smiley face.

The mood is sombre and quiet, even as a police helicopter loudly buzzes above us, reminding us of the tight security presence that includes many police officers lining the road, watching the proceedings.

Earlier I heard a group of people break out spontaneously in a mournful Jewish song, and several in the crowd joined them.

This is a local community deep in the throes of grief as they grapple with the aftermath of a horrific shooting.

Former England cricket captain Michael Vaughan heard gunshots as he visited a restaurant a few hundred yards away from where the attack took place with his family yesterday.

Vaughan tells BBC 5 Live he had been on the phone outside a restaurant near Bondi Beach when he saw "so many police cars flying by" before hearing what he thought were fireworks.

"Three or four minutes later I was shouted at to go inside," he says, explaining diners were locked inside the restaurant.

Vaughan explains it was around 30 or 40 minutes before he understood what was going on and at first he heard that hostages may have been taken on the beach.

The former cricketer describes the attack as the "lowest of the low" and praises a bystander who disarmed one of the gunmen.

"I can’t imagine how many lives that human being has saved," he says.

Rabbi Zalman Lewis, the cousin of British-born rabbi Eli Schlanger who was killed in the attack, has described his cousin as "caring, loving person who would do anything to help another person".

"He just loved people, I think this is the way I would want to remember," he tells BBC Breakfast.

He says his cousin had recently opened a community centre with his father-in-law in Sydney "to help people, to bring love" that he was "so proud of".

Lewis says his last interaction with his cousin was to congratulate him on the birth of his newborn son in October.

"If Eli was with us today, he would be telling people 'do good deeds, pray for the victims, pray for the families'," he adds.

Ahmed al Ahmed has been described as a "hero" bystander after he tackled one of the gunmen at Bondi Beach yesterday - successfully wrestling his gun off him.

Video footage showed the 43-year-old fruit shop owner and father of two running towards the gunman, seizing his weapon, before turning the gun on him and forcing his retreat.

In an interview with ABC News, Ahmed's parents say he was shot four to five times in his shoulder. We previously reported, citing 7News Australia, that he had been taken to hospital.

Mohamed Fateh al Ahmed and Malakeh Hasan al Ahmed told ABC they had been separated from their son since 2006 when he came to Australia. They landed in Sydney from Syria a couple of months ago, the organisation reported.

"He saw they were dying, and people were losing their lives, and when that guy [the shooter] ran out of ammo, he took it from him, but he was hit," his mother said, "we pray that God saves him."

"When he did what he did, he wasn't thinking about the background of the people he's saving, the people dying in the street," Mr Ahmed said.

"He doesn't discriminate between one nationality and another. Especially here in Australia, there's no difference between one citizen and another."

Health authorities in New South Wales have given an update on the victims of the Bondi Beach shooting who are receiving medical care.

We reported earlier 40 people had been taken to hospital.

NSW Health now says 27 patients are receiving care in hospitals across Sydney as of 17:00 local time (06:00 GMT) on Monday 15 December.

At least six remain in a critical condition, with others "critical but stable", and others stable.

"NSW Health extends its deepest sympathies to the families, friends and loved ones of those who died and were injured at Bondi Beach," a spokesperson says.

Fifteen people died in the Bondi Beach shooting, police say, with their ages ranging from 10 to 87.

Here's what's publicly known about them so far:

The family of British-born Rabbi Eli Schlanger, 41, told the BBC that he was among the dead. He had helped organise the Hanukkah event in Bondi and served as assistant rabbi, according to Jewish organisation Chabad, which hosted the event.

Also among the dead, according to the organisation, were Chabad member Reuven Morrison and Rabbi Yaakov Levitan, who was the secretary of the Sydney Beth Din, a Jewish religious institution.

Holocaust survivor Alex Kleytman was also killed at the shooting, which he had attended with his children and grandchildren, Chabad reported.

French citizen Dan Elkayam also died, French foreign minister Jean-Noël Barrot confirmed on X. "We mourn with his family and loved ones, with the Jewish community, and with the grieving Australian people," Barrot wrote.

The 10-year-old who police say is among victims has been identified by local media only as Matilda, as her family requested to withhold her surname. In a fundraiser set up for her family, Matilda's teacher described her as a "bright, joyful, and spirited child who brought light to everyone around her".

Another of the victims was Peter Meagher, a former policeman and local rugby club volunteer. He had been working as a freelance photographer at the Hanukkah event, Randwick Rugby Club said.

The Australian PM says on social media that he convened a national cabinet to respond to the "act of terror and antisemitism in Bondi last night".

"We stand with Jewish Australians and we stand against hatred and violence," writes Albanese on X.

"Australia is stronger than those who try to divide us and we will come through this together."

Earlier, Albanese announced that he would push for tougher gun laws at the meeting.

We've been reporting that the two gunmen involved in yesterday's shooting were a 50-year-old father, who died at the scene, and his 24-year-old son.

They have been named in local media as Sajid and Naveed Akram respectively.

"I think we're all still trying to process this. This is something I never dreamed in my lifetime I would see," said Allegra Spender, the independent MP for the electoral district of Wentworth which includes Bondi Beach.

She was speaking earlier to the BBC's Newhour radio programme on Monday.

Spender said the members of the Jewish community whom she has spoken to in the wake of the shooting were "going to bed in many cases scared".

"They're scared for their families," she said, adding that one person she had spoken to was taking down their mezuzah - a small scroll of parchment that Jewish people sometimes fix to the doorpost of their homes - for fear of being targeted.

"I think this is a night that we will remember in Australian history for many, many years," she said.

"And I think this is a wake-up call to Australia to say 'we cannot stand for this'."

Officials earlier today put out an urgent call for blood to help treat those injured in last night's shooting, and Sydney has responded in droves.

The blood donations website crashed under the weight of demand, so Lifeblood - the agency which manages them - appealed for people to show up at blood banks anyway.

Here at Town Hall, in the heart of Sydney, the wait to donate is over six hours.

Colt has already spent two hours in line but isn't leaving. "We can keep [the victims] in our thoughts and our prayers, but as far as tangible impacts, this is all we can do," the 21-year-old explains.

A little further down the line, 52-year-old Jim says the shooters' "cowardly" act had kept him up last night, and by morning he was resolved to help.

"I don’t necessarily agree with what is happening overseas, but that doesn’t mean that you open fire on innocent people here," he said. "They cannot justify [it] by saying there are dead children over there, so a… little girl should die here on the beach."

Gesturing to the line stretching out in the sun behind him, 21-year-old Alex Gilders said he hoped the city's reaction was a comfort to the Jewish community.

"Australia has your back."

About a 30-minute drive from Bondi Beach, an unremarkable, single-storey grey building with white window grilles is one of the main focuses of the police investigation.

This is the short-term rental property on Brighton Street in Campsie where police believe the two gunmen had been staying for the last fortnight or so, and where they prepared Sunday’s attack.

Within half an hour we saw at least ten officers from the Australian Federal Police and New South Wales Police going in and out.

So far I’ve spotted a black suitcase, several items wrapped in brown packaging and a full black plastic bin bag being removed and loaded into unmarked vehicles.

Several Muslim communities in Australia have issued condemnations of the Bondi attack.

Australian National Imams Council, a body representing imams and Muslims in the country, said in a statement: "While this attack has targeted the Jewish community, it is in reality an attack on all of us, including the Muslim community. This violent terrorist act constitutes an attack on all Australians."

"Antisemitism, expressed through hate, harassment, and violence directed at the Jewish community, has no place in our society," it added.

"We urge the community and representatives to reach out to their Jewish neighbours, friends, and colleagues to offer support and comfort during this difficult time."

The Alliance of Australian Muslims, which consists of Muslim organisations across the country, said in a statement that "those responsible must be held fully accountable and face the full force of the law".

Peter "Marzo" Meagher has been identified as one of the victims of the shooting, in a statement from the Randwick Rugby Club where he was a "much loved First Grade Manager and loyal club volunteer".

The statement, published about an hour ago, said that Meagher had served nearly 40 years in the NSW Police Force before retiring as a Detective Sergeant.

He was working as a freelance photographer at the Hanukkah event on Sunday when the shooting happened, the rugby club said.

"The tragic irony is that he spent so long in the dangerous front line as a Police Officer and was struck down in retirement while taking photos in his passion role" the statement said.

The club said that Meagher's death was "really hard to comprehend", and had "hit our players, coaches, managers, volunteers and supporters extremely hard".
