As news spread of the shooting at a synagogue in Pittsburgh, Jews — and Americans of all backgrounds — across the country were reeling from the shock. With at least 11 confirmed casualties, the Anti-Defamation League “believe[s] this is the deadliest attack on the Jewish community in the history of the United States.”

The alleged gunman, a 46-year-old white male named Robert Bowers, shouted “All these Jews need to die,” according to reports.

As details continue to emerge about the shooting, JTA took a look at other times U.S. Jewish institutions were targeted and the attackers’ affiliations.

The gunman later ended up walking into an FBI office and surrendering. Furrow was a white supremacist with ties to Aryan Nations, a neo-Nazi white supremacist group. Furrow, who said he hoped his attack would inspire others to target Jews, had considered attacking other Los Angeles Jewish organizations instead, including the Skirball Cultural Center and the Simon Wiesenthal Center. He was later sentenced to life in prison.

Naveed Afzal Haq shot six women at the Seattle Jewish Federation of Greater Seattle, killing one. He had entered by forcing a 14-year-old girl at gunpoint to buzz the building intercom. Once inside, he shot six people and called the police to tell them he had taken hostages. Haq eventually surrendered to the police. He killed one woman, Pamela Waechter, and wounded five others.
