Two people are in police custody at Bondi Beach in Sydney, the New South Wales Police Force said, after reports multiple gunshots were fired late Sunday.

Gunmen opened fire just after 18:30 on Sunday evening as hundreds of people attended the Chanukah by the Sea event to celebrate the start of the Jewish festival, the Sydney Morning Herald reported.

A police operation is ongoing, they said, urging people to avoid the area.

Australian Broadcasting Corporation showed footage of two black-clad gunmen firing on people, and several people being treated by police and paramedics.

There are multiple fatalities and at least ten people injured, according to early reports. Two police officers were also injured.

Earlier, police said they were responding to a developing incident.

“Police are responding to a developing incident at Bondi Beach and are urging the public to AVOID the area.,” the New South Wales police said in a post on X. “Anyone at the scene should take shelter. Police are on scene and more information will be provided when it comes to hand.”
