Sydney, Australia (CNN) — At least 11 people were killed in a terror attack on Sunday targeting the Jewish community celebrating the first night of Hannukah at Sydney’s famed Bondi Beach. “In light of the horrific antisemitic terrorist attack that took place today in Sydney, Australia, during a celebration of the first night of Chanukah, the Jewish Federation of Greater Indianapolis (JFGI) and the Indianapolis Jewish Community Relations Council (JCRC) stand united with our brothers and sisters around the world in grief and resolve.” Around 1,000 people gathered on a grassy area at Archer Park when at least two gunman opened fire at 6:47 p.m. local time, sending panicked crowds running in all directions. One suspect was killed at the scene, while the other was injured and taken into custody. Police believe a third suspect may have been involved, but they cautioned against speculation as investigations continue. It’s Australia’s worst mass shooting since a massacre almost 30 years ago saw the country introduce some of the world’s toughest gun laws. Here’s what we know: Multiple fatalities confirmed At least 11 people died when the gunman started shooting less than two hours into a Hanukkah event. A 12-year-old girl and a rabbi are among the victims, Alexander Ryvchin, co-chief executive of the Executive Council of Australian Jewry, told CNN. The event was advertised to have “live entertainment, music, games and fun” for all ages. Families had gathered on the grass, swimmers were in the ocean, and witnesses remember seeing people dancing and banging drums. Twenty-nine people were injured and taken to hospitals around the city. New South Wales Police were unable to confirm the ages of those killed and injured but earlier specified that children and families were attending the event. Police set up an exclusion zone around a car found parked on Campbell Parade which they believed was fitted with “several improvised explosive devices.” The rescue bomb disposal unit worked on the vehicle, and police later confirmed the IEDs had been removed. Hero praised In one video circulated widely online, a man in a white shirt is seen tackling one of the gunmen and taking his firearm. His actions were praised by Australian authorities. “That man is a genuine hero, and I’ve got no doubt that there are many, many people alive tonight, as a result of his bravery,” said New South Wales Premier Chris Minns. Australian Prime Minister: ‘An act of evil’ Australian Prime Minister Anthony Albanese convened a meeting of the National Security Committee on Sunday evening and condemned the attack. “This is a targeted attack on Jewish Australians on the first day of Hanukkah, which should be a day of joy, a celebration of faith, in faith, an act of evil, anti-semitism, terrorism that has struck the heart of our nation,” Albanese said in public remarks. ...read more read less
