Mayor-elect Zohran Mamdani on Sunday denounced the shooting on Sydney, Australia’s Bondi Beach during a Hanukkah celebration that killed 16 people and left 29 others injured.

“The attack at a Hanukkah celebration in Sydney today was a vile act of antisemitic terror,” Mamdani wrote in part in an X post. “I mourn those who were murdered and will be keeping their families, the Jewish community, and the Chabad movement in my prayers. May the memories of all those killed be a blessing."

Australian authorities say one gunman was fatally shot by police and a second was arrested and is in critical condition.

Two police officers were wounded during the shooting.

The massacre followed a wave of antisemitic attacks in Australia, although authorities didn't link them to this shooting. Prime Minister Anthony Albanese called it “an act of evil, antisemitism, terrorism.” The attack targeted a Jewish celebration called Chanukah by the Sea, marking the start of Hanukkah.

Mamdani, the city’s first Muslim mayor, promised to “keep Jewish New Yorkers safe.”

“When I am Mayor, I will work every day to keep Jewish New Yorkers safe—on our streets, our subways, at shul, in every moment of every day. Let this be a purpose shared by every New Yorker, and let us banish this horrific violence to the past.
