Multiple sites in Sydney's eastern suburbs have been vandalised in what has been labelled as an "appalling and shameful" attack by NSW Premier Chris Minns and "heartbreaking" by the education industry.

Chris Minns is two years away from an election, so he can ride out these bad times, but an angry, scared Sydney is a big risk for Anthony Albanese.

Jewish residents already fear for their lives following an escalating series of antisemitic attacks across the city. Places of worship have been vandalised. A childcare centre near a Maroubra synagogue has been firebombed.

The public only found out about the caravan after news of its discovery was leaked to the media, 10 days after it was found. Now the Jewish community has responded.

Three more incidents of anti-Semitic graffiti were found across Sydney yesterday morning, leading Australian political leaders to warn of an escalation in hatred and decry as terrorism explosives found earlier in a trailer on the city’s outskirts.

Police found “an amount” of powergel explosives in the caravan, enough to create a 40-metre blast radius, along with notes and the address of a Sydney synagogue inside. Powergel is the brand name for a range of “high-strength” explosives used in the mining industry.

Anthony Albanese was kept in the dark about a planned terror attack on prominent Jewish sites in Sydney, senior police sources have revealed.

NSW Police were contacted about the caravan, which had power gel explosives with the potential to a cause a "mass casualty event", alongside a document with both antisemitic sentiments and a list of targets.

New South Wales Premier Chris Minns has strongly condemned the “horrifying” antisemitic attack in Sydney’s east during a press conference.

A disturbing note and powerful explosives strong enough to create a 40-metre blast radius were found inside a Sydney caravan police say was intended for a “mass casualty” anti-Semitic attack.

SYDNEY, Jan. 30 (Xinhua) -- The owner of a caravan found filled with explosives in northwest Sydney, the capital city of Australia's state of New South Wales (NSW), is already in police custody, authorities have said.

A caravan containing explosives and documents suggesting plans to target the Jewish community has been labelled a terrorist threat by the NSW premier, who said the objects could have led to a "mass casualty event".
