A car displaying a "Happy Chanukah" sign was set on fire in Melbourne, Australia, in what authorities are investigating as a suspicious incident. The event occurred days after a mass shooting at a Hanukkah festival in Sydney that killed 15 people. Jewish community leaders have called the Melbourne car fire an act of antisemitism, expressing concerns about escalating hate crimes and the safety of the Jewish community. Police are actively searching for a person of interest in connection with the fire.
