At least 12 people are dead after two gunmen opened fire at Sydney’s famed Bondi Beach in an attack authorities said targeted the Jewish community during a major holiday celebration.

One of the shooters is among the dead while the second is in a critical condition, local police said in a statement. More people have been injured, among them two police officers, authorities said. Police are investigating whether any other assailants were involved.

“This attack was designed to target Sydney’s Jewish community, on the first day of Hanukkah,” said Chris Minns, the premier of the state of New South Wales. “What should have been a night of peace and joy celebrated in that community with families and supporters, has been shattered by this horrifying evil attack.”

The attack occurred as hundreds of members of Sydney’s Jewish community gathered in Bondi Beach for the annual Hanukkah celebration, among the biggest events of the local Jewish calendar. The event, attended by many families, features the lighting of the menorah, a petting zoo, a children’s climbing wall and other activities.

Australian Prime Minister Anthony Albanese said his “thoughts are with every person affected.”

Israel’s President Isaac Herzog called the attack terrorism: “Our hearts go out to our Jewish sisters and brothers in Sydney who have been attacked by vile terrorists as they went to light the first candle of Chanukah.”

European Commission President Ursula von der Leyen sent “heartfelt condolences” and said “Europe stands with Australia and Jewish communities everywhere,” in a statement.

“This appalling act of violence against the Jewish community must be unequivocally condemned,” said Kaja Kallas, the EU’s chief diplomat.

The incident is Australia’s worst mass shooting in decades, after the nation’s gun laws were tightened in response to a 1996 massacre in the state of Tasmania.
