A shooting spree on Nov. 2 in Vienna near the Austrian capital’s main synagogue, Stadttempel, killed four people and injured 15. Authorities said the gunman was an Islamic sympathizer.

The first shots were fired at about 8 p.m. in Seitenstettengasse, where Vienna’s main synagogue is located. Witnesses said they heard between 100 and 200 shots. Rabbi Schlomo Hofmeister, Vienna’s chief rabbi, who was in the area, said in an interview with the state broadcaster, that he first assumed the gunfire was fireworks, but then saw an armed man shooting at people in pubs and bars near the synagogue.

The attack began near the synagogue, but eventually shots were fired at six locations throughout the First District. Two women, two men and the gunman were killed in the spree.

About 8,000 Jews live in Vienna. Austrian police confirmed that the assailant was armed with an automatic weapon. He was killed in an exchange of fire with the police.
