VANCOUVER, British Columbia (AP) — The Jewish Federation of Greater Vancouver said Friday an “incendiary device” was thrown at the front doors of a synagogue in what Canadian Prime Minister Justin Trudeau called a “disgusting act of antisemitism.”

Vancouver police said the case was being investigated as an act of arson and possible hate crime.

The federation said in a statement the incident occurred at the Schara Tzedeck synagogue at around 9:30 p.m. on Thursday and that damage was minor and no one was hurt.

The federation calls the alleged incident a “deliberate act of hate” and an “attempt to intimidate” the Jewish community.

Rabbi Andrew Rosenblatt said people were inside the synagogue after services around 9:20 p.m. on Thursday when they heard a “bang” outside.

But it was a passerby who alerted them that their building was on fire, before a member of the synagogue put out the flames with his jacket, said Rosenblatt while pointing to the scorched front door on Friday morning.
