Rabbi Eli Schlanger, 41, died when two gunmen targeted a Hanukkah celebration at a park next to the beach on the first day of the Jewish festival of lights on Sunday evening.

One of the attackers has been confirmed dead, in addition to the 11 people killed, while the second is in a critical condition police said.

Mr Schlanger was assistant rabbi at Chabad of Bondi, a Jewish cultural centre, according to Jewish News.

His first cousin, Brighton-based Rabbi Zalman Lewis, told the paper: "How can a joyful rabbi who went to a beach to spread happiness and light, to make the world a better place, have his life ended in this way?

"We can only respond by doing what Eli would have wanted, what he dedicated his life to - doing more mitzvot (good deeds) and to keep spreading positive energy."

Mr Schlanger was reportedly a father of five who, along with his wife Chayala, celebrated the birth of their youngest child, a boy, two months ago, and grew up in Temple Fortune, north London.

His cousin, who described him as "vivacious, optimistic and full of energy and life", also paid tribute to him on social media.

"Please don't send sympathy messages," he wrote. "My dear cousin, Rabbi Eli Schlanger was murdered in today's terrorist attack in Sydney. He leaves behind his wife & young children, as well as my uncle & aunt & siblings."

Another one of his cousins, Rabbi Dovid Lewis, of the South Manchester Synagogue, told Sky News he had "dedicated his life to adding light and to spreading Torah and Judaism".

"There's a feeling of numbness but there's also a feeling he lived," he said.

"I'm not going to wallow in pity, I'm going to do something in his memory."

He said his cousin "lit a light", adding: "I'm now obliged to pick up that light and become a torch bearer…

"We have got to say darkness can only be combatted with light. It's what he did, it's what I will do, it's what we ask everyone else to do as well."

Israel's foreign ministry has said one of the country's citizens is also among those killed.

Parents messaged their children and teenagers, who had been enjoying a late afternoon swim at Bondi.

Witnesses said police were on the scene quickly, and the streets of Sydney's eastern suburbs were full of police cars and ambulances on their way to Bondi.

When we arrived, there were still dozens of people processing what had happened, and everywhere - shock.

Witnesses told us that when the gunfire started some people took cover in the North Bondi Surf Life Saving Club. Once the threat was over, lifeguards helped the injured and used surfboards to carry them out.

Some people were clearly traumatised and provided graphic detail of witnessing the shooting and seeing people killed in front of them.

A photographer, Danny, was covering the Jewish holiday event.

He said he "locked eyes" with one of the gunmen, who then fired towards him. Danny said he was grazed by a bullet. He kept filming during the shooting, while taking cover.

Sam, from France, was working at Bondi. He went to the scene of the attack and saw almost a dozen people lying on the ground covered in blood. Sam described it as like a "war zone".

Rabbi Lei Wolff, from Central Synagogue in Sydney, went to Bondi as soon as he heard about the mass shooting. A dear friend of his, Rabbi Eli Schlanger, was killed in the attack.

Rabbi Wolff has called on people around the world to stand with Australia's Jewish community against terrorism.

The man, named by a relative as 43-year-old Ahmed al Ahmed, was seen in a video running up to the attacker from behind and then grabbing the shotgun from his hands before pointing the weapon back at him.

The footage then showed the terrorist heading towards a bridge where another gunman was located, while the bystander placed the gun beside a tree.

Mr Ahmed, who was wearing a white T-shirt, was shot twice in the incident and was due to have surgery, his cousin, Mustafa, has revealed.

In a video on 7News, Mr Ahmed appeared to have a bloodied arm and hand, and was helped by other people near the scene in the Australian city.

At least 11 people were killed and 29 others injured in the attack when two gunmen opened fire from a bridge on crowds at a Jewish event around 6pm local time on Sunday evening.

More than 1,000 people had been at the gathering which was celebrating the festival of Hanukkah.

A gunman was killed and another was in a critical condition following the shooting.

One of the suspects was 24-year-old Naveed Akram.

His driver's licence says he lives in Bonnyrigg, a suburb of Sydney. The identity of the other suspected attacker is not known.

Mustafa said father-of-two Mr Ahmed, who owns a fruit shop in the Sydney suburb of Sutherland, did not have any experience with guns but was just walking past when he decided to step in.

He told 7News: "He's in hospital and we don't know exactly what's going on inside.

"We do hope he will be fine. He's a hero, 100%."

The footage of the bystander's actions spread quickly on social media as people praised the man for his bravery, saying his actions had potentially saved many lives.

"Australian hero (random civilian) wrestles gun off attacker and disarms him. Some people are brave and then some people are... whatever this is," one person said on X, sharing the video.

"This Australian man saved countless lives by stripping the gun off one of the terrorists at Bondi beach. HERO," another said.

Chris Minns, the premier of New South Wales state, where Sydney is located, said it was the "most unbelievable scene I've ever seen".

"A man walking up to a gunman who had fired on the community and single-handedly disarming him, putting his own life at risk to save the lives of countless other people."

"That man is a genuine hero, and I've got no doubt that there are many, many people alive tonight as a result of his bravery," he added.

The country's prime minister Anthony Albanese praised the actions of Australians who had "run towards danger in order to help others".

"These Australians are heroes and their bravery has saved lives," he told a news conference.

Shabana Mahmood said the dedicated units will be in place across every force by 2029 as part of Labour's violence against women and girls (VAWG) strategy due to be launched later this week.

The use of Domestic Abuse Protection Orders (DAPOs), which had been trialled in several areas, will also be rolled out across England and Wales. They are designed to target abusers by imposing curfews, electronic tags and exclusion zones.

The orders cover all forms of domestic abuse, including economic abuse, coercive and controlling behaviour, stalking and 'honour'-based abuse. Breaching the terms can carry a prison term of up to five years.

Nearly £2m will also be spent funding a network of officers to target offenders operating within the online space.

Teams will use covert and intelligence techniques to tackle violence against women and girls via apps and websites.

A similar undercover network funded by the Home Office to examine child sexual abuse has arrested over 1,700 perpetrators.

Abuse is 'national emergency'

Challenged on Sunday Morning with Trevor Phillips on the amount of funding and whether it could be effective, Ms Mahmood said it would be a "pilot scheme for 18 months" because "we've never gone into the online space looking at violence against women and girls".

"We'll be setting out more of our proposals on those specifics later in the coming week," she said.

"But I think it is important that the state take some action because, you know, we're not willing to sit back and just accept that violence against women and girls is a fact of life.

"And I think for too long across society, it's just something that we expect is just something that's normal. And we're calling time on that."

The target to halve violence against women and girls in a decade is a Labour manifesto pledge.

The government said the measures build on existing policy, including facial recognition technology to identify offenders, improving protections for stalking victims, making strangulation a criminal offence and establishing domestic abuse specialists in 999 control rooms.

Ms Mahmood went on to say there was a "postcode lottery" for victims and survivors in terms of what response they receive if they lodge an allegation.

"We want to turn that around," she said. "That's why we think it has to be a national programme of making sure that these teams are rolled out across the country."

Labour has 'failed women'

But the Conservatives said Labour had "failed women" and "broken its promises" by delaying the publication of the violence against women and girls strategy.

Shadow home secretary Chris Philp said that Labour "shrinks from uncomfortable truths, voting against tougher sentences and presiding over falling sex-offender convictions. At every turn, Labour has failed women".

Nine people, all or nearly all of whom are also believed to be students, were injured in the attack at around 4pm (9pm UK time) on Saturday.

Eight people have been described as stable, although one remains critically ill. Another person has left hospital.

A video released by officials shows a suspect walking down a street away from the campus and turning a corner, dressed in dark, loose-fitting clothing.

FBI Director Kash Patel posted details of the arrest at a Hampton Inn hotel in Coventry, about 20 miles (32km) from Providence, early on Sunday, "based off a lead" from Providence police.

Authorities said the suspect was in their 20s, younger than was initially reported by police, but no further details have been released about them.

Providence police chief Colonel Oscar Perez told reporters on Sunday that the investigation is "complex" and progressing "extremely fast", but refused to elaborate.

The shooting happened inside a classroom on the first floor of the Barus & Holley engineering building, a seven-storey structure home to much of the university's engineering and physics study and research.

Brown University provost Frank Doyle confirmed that final exams were taking place in the engineering building when the gunman opened fire.

A police official told the AP news agency that the gunman fired more than 40 9mm rounds. A gun has not been recovered, but officers did seize two loaded 30-round magazines.

Providence mayor Brett Smiley said the order to shelter-in-place for nearby neighbourhoods had been lifted, but some streets remained shut as investigators work at the scene.

"The people of Providence should breathe a little easier this morning," Mr Smiley added.

Access to parts of the campus remained restricted on Sunday as police maintained a security perimeter around Minden Hall and nearby apartment buildings.

The site has hundreds of buildings, including lecture halls, laboratories and dorms.

Brown is a private university with roughly 7,300 undergraduate students and more than 3,000 graduate students.

Students hid under desks

Student Chiang-Heng Chien said he was working in one of the labs with three other students when they received a notification about a shooting nearby.

"We decided to turn the light off and close all the doors and hide under our desks, and wait for the next notification after the shooting," he told reporters.

The students hid under the desks for about two hours.

"I was hoping that no one's getting hurt and no one's dead," he said.

The students left the building when they received another notification, and security personnel moved in to search the facility.

Emma Ferraro, a chemical engineering student, was in the Barus & Holley lobby working on a final project when she heard loud popping sounds coming from the eastern side of the building.

For a moment, everyone paused and looked around, she recalled.

Once Ferraro realised the sounds were gunshots, she rushed to the door and ran to a nearby building, where she had been sheltering for the past few hours.

One person who was initially thought to be involved in the shooting was detained but was later determined to have no involvement.

President Donald Trump told reporters at the White House that he had been briefed on the situation, which he called "terrible".

"All we can do right now is pray for the victims and for those that were very badly hurt," he added.
