Describing the mass shooting that killed at least 16 people at Sydney's Bondi Beach on Sunday as a "pure evil" act of antisemitism, Australian Prime Minister Anthony Albanese on Monday said flags would fly at half-mast to honor the lives lost in the attack, Australia's ABC News reported Monday.

Albanese said that Australia would do whatever is necessary to stamp out antisemitism.

"It is a scourge and we'll eradicate it together," he said.

The death toll from a shooting has risen to 16, with a father and son identified as the attackers, police in the state of New South Wales (NSW) said Monday.

It marks Australia's most deadly mass shooting since 35 people were killed at Port Arthur in the island state of Tasmania in 1996, which prompted fundamental changes to Australia's gun ownership laws, according to the Xinhua News Agency.

According to Australia's media outlet ABC News, New South Wales Premier Chris Minns says the attack was designed to target Sydney's Jewish community, according to the report.

Multiple global leaders have voiced condemnation over the mass shooting.

UN Secretary General Antonio Guterres said on X he was "horrified" by the "heinous deadly attack". "My heart is with the Jewish community worldwide," he said.

US President Donald Trump said during a Christmas celebration at the White House that the attack in Bondi was "terrible" and "purely antisemitic", ABC reported.

EU chief Ursula von der Leyen said in an X post on Sunday she was "shocked" by what she condemned as an "appalling act of violence."

According to SCMP on Monday, UK Prime Minister Keir Starmer called the attack "sickening" and "deeply distressing", and sent condolences to "everyone affected by the appalling attack".

German Chancellor Friedrich Merz said on X on Sunday that "the antisemitic attack at Bondi Beach during Hanukkah leaves me utterly shocked. My thoughts are with the victims and their families." He said "This is an attack on our shared values. We must fight antisemitism here in Germany and around the world."

Indian Prime Minister Narendra Modi wrote on X on Sunday that he "strongly condemns the ghastly terrorist attack," which targeted "people celebrating the first day of the Jewish festival of Hanukkah." "On behalf of the people of India, l extend my sincere condolences to the families who lost their loved ones," Modi added.

The President of Pakistan's official account wrote on X on Sunday that "Asif Ali Zardari has expressed sorrow over the tragic shooting in Sydney." He also condemned violence against innocent civilians. According to Arab News, Pakistani Prime Minister Shehbaz Sharif wrote on X that "Pakistan condemns terrorism in all its forms and manifestations." 

Consulate-General of China in Sydney stated Monday morning that no reports of Chinese citizens killed or injured in Australian shooting so far. The Consulate-General urges Chinese citizens in the local area to avoid traveling to the incident site.

Israeli Prime Minister Benjamin Netanyahu, during a government meeting in Dimona on Sunday, praised Ahmed al-Ahmed, a bystander who has tackled and disarmed one of the gunmen during the Bondi Beach attack, according to Euronews.

"We saw an action of a brave man — turns out a Muslim brave man, and I salute him — that stopped one of these terrorists from killing innocent Jews," Netanyahu said. He criticized Australian Prime Minister Anthony Albanese, saying he had warned him that Australia's policies "fuel antisemitism."

According to media reports, a police statement said that 14 people died at the scene and two others died in hospital.

The deceased range in age from 10 to 87 years old.

Another 40 people were being treated in hospital for their injuries as of Monday morning, five of whom were in critical condition.

NSW Police Force Commissioner Mal Lanyon told a press conference on Monday morning that the two alleged shooters were a 50-year-old man and his 24-year-old son.

The 50-year-old, who was killed at the scene, was a licensed firearm holder with six guns legally in his possession, Lanyon said.

Lanyon, who on Sunday night officially declared the shooting as a terrorist attack, said Monday that investigations into motives behind the attack are ongoing.

A bystander who is being hailed as a hero for tackling one of the gunmen during the Bondi Beach attack has been undergoing surgery after being wounded in the attack, CNN reported Sunday.

Euronews reported Sunday night that the bystander has been identified as Ahmed al-Ahmed, a 43-year-old fruit shop owner from Sydney's Sutherland Shire.

According to the report, video footage shows Ahmed, wearing a white T-shirt, charging one of the shooters from behind, wrestling away his rifle and then pointing it at the attacker, who retreated towards a bridge where the second gunman was positioned. Ahmed then placed the rifle against a tree and raised his hands, apparently to signal to police he was not a threat.

During the struggle, Ahmed was shot twice by the second gunman — once in his arm and once in his hand. He underwent surgery on Sunday night and is recovering, the report added.
