Australian authorities say they’ve foiled a potential “mass casualty” attack with the discovery of a trailer packed with explosives in northwest Sydney, and “an indication” it was to be used against targets in the Jewish community following a spate of antisemitic incidents.

Australia has been grappling with a spate of antisemitic attacks on synagogues, buildings and cars since the beginning of the Israel-Gaza war in late 2023.

The explosives located in a caravan could have caused a 'potential mass casualty event', authorities have said.
