SYDNEY (AP) — An attack at a famous Australian beach killed 16 people, including a child, officials said Monday, after two gunmen opened fire at a Hanukkah celebration on Sydney’s Bondi Beach. Prime Minister Anthony Albanese called it an act of antisemitic terrorism.

Hundreds of people had gathered Sunday at the beach for an event to celebrate the first day of Hanukkah, when gunmen opened fire. At least 38 others were injured in the attack.

New South Wales Health Minister Ryan Park said the death toll had risen from 12 to 16 overnight, including a 12-year-old child. Three other children are being treated in hospital, he said.

“This is absolutely horrendous for the community broadly, but particularly the Jewish community. … What we saw last night was the worst of humanity, but at the same time, the very best of humanity,” Park said.

The massacre at one of Australia’s most popular beaches followed a wave of antisemitic attacks that have roiled the country over the past year, although the authorities didn’t suggest those and Sunday’s shooting were connected. It is the deadliest shooting in almost three decades in a country with strict gun control laws.

One gunman was fatally shot by police and the second was arrested and in critical condition, authorities said. Police said one gunman was known to security services, but there was no specific threat.

At least 29 people were confirmed wounded, including two police officers, said Mal Lanyon, police commissioner for New South Wales state, where Sydney is located.

Police said officers were examining a number of suspicious items, including improvised explosive devices found in one of the suspect’s car.

“This attack was designed to target Sydney’s Jewish community,” New South Wales Premier Chris Minns said.

The violence erupted at the end of a summer day when thousands had flocked to Bondi Beach, including hundreds gathered for the Chanukah by the Sea event celebrating the start of the eight-day Hanukkah festival.

Chabad, an Orthodox Jewish movement that runs outreach around the world and sponsors public events during major Jewish holidays, identified one of the dead as Rabbi Eli Schlanger, assistant rabbi at Chabad of Bondi and an organizer of the event.

Israel’s Foreign Ministry confirmed the death of an Israeli citizen, but gave no further details.

Police said emergency services were called to Campbell Parade in Bondi about 6:45 p.m. responding to reports of shots being fired. Video filmed by onlookers showed people in bathing suits running from the water as shots rang out. Separate footage showed two men in black shirts firing with long guns from a footbridge leading to the beach, as sirens wailed and people cried out in the background.

One dramatic clip broadcast on Australian television showed a man appearing to tackle and disarm one of the gunmen, before pointing the man’s weapon at him, then setting the gun on the ground.

Minns called the man, named by relatives to Australian media as fruit shop owner Ahmed al Ahmed, a “genuine hero.”

Arsen Ostrovsky, a lawyer attending the Hanukkah ceremony with his wife and daughters, was grazed in the head by a bullet. Ostrovsky said he moved from Israel to Australia two weeks ago to work for a Jewish advocacy group.

“What I saw today was pure evil, just an absolute bloodbath. Bodies strewn everywhere,” he told The Associated Press in an email from the hospital. “It was like reliving Oct. 7 all over.”

“I never thought would be possible here in Australia.”

Lachlan Moran, 32, from Melbourne, told the AP he was waiting for his family when he heard shots. He dropped the beer he was carrying and ran.

“I sprinted as quickly as I could,” Moran said. He said he heard shooting off and on for about five minutes. “Everyone just dropped all their possessions and everything and were running and people were crying and it was just horrible.”
