Multiple people have been killed in a horror mass shooting at Sydney's Bondi Beach, 9News understands.
Ten people have been killed and dozens more injured in a horror mass shooting at Sydney's Bondi Beach.
Two gunmen opened fire on the popular beach, with vision from the scene showing them shooting from a footbridge at the southern end of Campbell Parade this evening, shortly before 7pm (AEDT).
Dozens of people have been shot, 10 of whom have died, including one of the shooters.

The other shooter is critically injured and in police custody.
Police have cautioned that the bridge the shooters used may have had explosives hidden on it and is being searched for possible live bombs.
Dozens more people have been injured, including two police officers as well as young children, with at least 25 patients taken to hospital.
"I saw children, I saw an elderly woman," 9News reporter Damien Ryan said from the scene.

"Families there, little children wounded, blood all over them."
Two police officers have also been shot in what is Australia's worst mass shooting since the Port Arthur massacre in 1996.
The sheer number of injuries has meant the wounded have been taken to hospitals all over Sydney, from nearby Prince of Wales and St Vincent's to Westmead in the city's west and St George in the south.
The shooting came at the same time as a Jewish event was being held at the beach, on the first day of Hanukkah.

Footage from the scene showed hundreds, if not thousands, of beachgoers fleeing Bondi as gunshots rang out.
Vision also captured the moment a good Samaritan snuck up on one of the gunmen, tackling him from behind and wrestling his gun off him.
The man then turned the weapon on the attacker, holding it at him as the man stumbled backwards, holding up his hand as he scrambled away.
The heroic man did not fire the gun but signalled for assistance.
Police issued an alert just before 7pm, urging the public to avoid the area due to the "developing incident".
"Anyone at the scene should take shelter," NSW Police said.
"Police are on scene and more information will be provided when it comes to hand."
The prime minister has been briefed by federal police on the incident, and a meeting of the National Security Committee has been called.

"The scenes in Bondi are shocking and distressing. Police and emergency responders are on the ground working to save lives. My thoughts are with every person affected," Anthony Albanese said.
"I have just spoken to the AFP commissioner and with the NSW premier. We are working with the NSW Police and will provide further updates as more information is confirmed."
NSW Premier Chris Minns urged the public to follow the advice from authorities.
"The reports and images coming out of Bondi tonight are deeply distressing," he said.
Police and emergency services are responding and the public should follow official advice.
"We will update the public as soon as more information becomes available."
Police are expected to provide an update about 10pm. They have asked witnesses to provide them with any vision of the incident via this link.
More to come.
