Australian Prime Minister Anthony Albanese has vowed to strengthen gun laws after a shooting targeting the country’s Jewish community at a Hanukkah event on Sydney’s Bondi Beach.

Fifteen people including a 10-year-old girl were killed in the attack, which Albanese described as an “act of antisemitism… [and] terrorism”.

The two gunmen were identified by police as a father and son. The older man was shot dead by police, while the pounger is in a critical condition in hospital.

Two Islamic State (IS) group flags were found in their car, a senior official told ABC News.

Mass shootings in Australia are very rare. This attack is the country’s deadliest incident since 1996, when a gunman killed 35 people during the Port Arthur massacre.

Police have declared the incident a terrorist attack.

Here is what we know so far.

On Sunday 14 December, at 18:47 (07:47 GMT), police received reports of gunfire at a park in Bondi Beach.

Verified videos captured people fleeing the beach, screaming and running as a gunshots rang out.

Some footage appears to show two gunmen firing from a small bridge near a car park on Campbell Parade, on the northern end of Bondi Beach. They are firing down towards an area of parkland where the Hanukkah event is taking place.

Separate video from a few minutes later shows a bystander – since identified as Ahmed al Ahmed – disarming one of the gunmen. Mr al Ahmed, a fruit shop owner and father-of-two, tackles the gunman, seizes his gun and turns it back on him.

The gunman then retreats towards the bridge, from where another attacker is firing.

In the same footage, another man – who appears to be injured – is seen fleeing the scene, as police arrive and begin to fire in the direction of the gunmen.

Another verified video shows several police officers on the same bridge. One appears to be administering CPR to a motionless man as someone shouts: “He’s dead, he’s dead.”

At 18:57, New South Wales Police share their first public statement, urging people at the scene to take shelter and others to avoid the area.

At 19:39, police say two people are in custody while at 22:00, New South Wales Police designate the incident as a terrorist attack on Sydney’s Jewish community.

A 10-year-old girl was among 15 people killed in the attack, according to New South Wales Police. Two rabbis and a Holocaust survivor were also killed.

The ages of the victims range from 10 to 87.

The family of British-born Rabbi Eli Schlanger, 41, told the BBC he was among the dead. He had helped organise the Hanukkah event, Jewish organisation Chabad said.

Rabbi Schlanger’s cousin, Rabbi Zalman Lewis, described him as “vivacious, energetic, full of life and a very warm outgoing person who loved to help people”.

Also among those killed was Rabbi Yaakov Levitan, described as a “popular co-ordinator” of Chabad activities in Sydney.

Alexander Kleytman, a Holocaust survivor, was killed while trying to shield his wife, Chabad says.

Israeli media report that an Israeli citizen was also killed.

French citizen Dan Elkayam was also identified as a victim of the attack.

A further 42 people were taken to hospital due to their injuries. Australian health authorities say 27 people are being treated in hospitals across Sydney, and six of them are in a critical condition.

New South Wales Health Minister Ryan Park told ABC News on Monday that four children had been transferred to Sydney Children’s Hospital. It is not clear if the 10-year-old child who died is included in this number.

Two police officers were shot and injured during the incident, according to police. They were reported on Sunday to be in a “serious, verging on critical” condition.

The pair have since been named by local media as Sajid Akram, 50, and his son Naveed Akram, 24.

Sajid Akram was a licensed firearms holder, having met the eligibility criteria for a recreational hunting licence. He was linked to six firearms, all of which were believed to have been used in the attack, New South Wales Police Commissioner Mal Lanyon said.

The father arrived in Australia in 1998 on a student visa, Home Minister Tony Burke said, without specifying from where. The visa was transferred in 2001 to a partner visa and later resident return visas.

Naveed Akram is an Australian-born citizen. Albanese said he had first come to the attention of authorities in October 2019.

He had been “examined on the basis of being associated with others”, Albanese said, “and the assessment was made that there was no indication of any ongoing threat or threat of him engaging in violence”.

Australian broadcaster ABC reports that the 24-ysear-old was examined over his close ties to a Sydney-based IS cell. ABC also reports that counter-terrorism police believe the gunmen pledged allegiance to IS.

Two IS flags were found in the Bondi Beach gunmen’s car, a senior official told ABC. A flag could be seen on the bonnet of the car in footage from the scene, the broadcaster reports.

Albanese told ABC that although the gunmen were acting alone and not as part of a cell, they were “clearly” motivated by “extremist ideology”.

Albanese has said that he will put tougher new gun laws on the agenda for a national cabinet meeting.

These will include proposals to limit the number of guns that can be used or licensed by individuals, and a review of licences over a period of time.

Australia has some of the world’s most stringent gun laws. Permits and licenses are required to own guns while all people who own firearms also have to be registered.

In other reaction:

• US Secretary of State Marco Rubio had a phone call with Australian Foreign Minister Penny Wong to “discuss the antisemitic terrorist attack”
• Israeli President Isaac Herzog called the shooting a “very cruel attack on Jews”
• King Charles III – who is head of state in the Commonwealth nation – said he was “appalled and saddened by the most dreadful antisemitic terrorist attack”
• New South Wales Premier Chris Minns asked people to continue laying flowers at a memorial site at the rear of the Bondi pavilion. He also welcomed the “record numbers” of people and massive lines at blood donation services across New South Wales.

Hanukkah, or Chanukah in Hebrew, is often referred to as the Jewish festival of lights.

It reminds Jewish people of when they won a battle against Greeks to practise their religion freely, more than 2,000 years ago.

The date changes but it always falls in November or December.

An event to mark the first day of the celebration was taking place on Bondi Beach at the time of the shooting.

A digital flyer for the event, named Chanuka by the Sea 2025, shows it was scheduled to take place near the beach’s children’s playground from 17:00.

Organised by Chabad, the event was set to feature live entertainment and activities “for all ages”. Around 1,000 people were said to be in attendance.
