Australian law enforcement agents in Sydney have found a caravan loaded with explosives and containing a list of Jewish targets, they said on Wednesday.

A major counterterrorism investigation is underway following the discovery, which happened on Jan. 19 and follows a wave of at least 10 antisemitic attacks in Australia in recent months, New South Wales Police Deputy Commissioner David Hudson told reporters.

The note referencing Jewish addresses and a synagogue contained the words “f*** the Jews,” according to the Daily Mail.
