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.

Australian police suspect explosives stashed on Sydney’s outskirts were evidence of a deadly escalation in a campaign of antisemitic arson and graffiti crimes that has been waged in major cities for months,

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

Australian authorities say they are investigating links to overseas actors as they crack down on antisemitic violence.

Australian Prime Minister Anthony Albanese has said the discovery of a caravan packed with explosives in outer suburban Sydney was part of a terrorist plot, with local officials drawing a link between the find and a recent spate of antisemitic attacks.

Australian Jewish Association President David Adler has condemned the latest antisemitic incident to affect New South Wales.
