A man accused of attempting to set fire to a synagogue in Sydney has been linked to two other anti-Semitic attacks, including targeting a prominent Jewish leader's former home. The accused, Leon Sofilas, has been charged with being an accessory before the fact to the incidents. The revelations come as Australia's spy chief warns of increasing anti-Semitism and tension within the Australian Jewish community. The nation has seen a recent spate of hate crimes, with threats transitioning from harassment to specific targeting of Jewish communities and prominent figures.
