Shooting the 'deadliest anti-Semitic attack in recent US history'

A gunman shouting "all Jews must die" burst into a Pittsburgh synagogue during a circumcision ceremony on Saturday, shooting dead 11 people.

Robert Bowers, 46, wielding an arsenal that included a semi-automatic rifle and three handguns, also left six others wounded, including four police officers, during the 20 minute attack.

The shooting happened at the Tree of Life Congregation in a leafy suburb in the heart of its Jewish community in Pennsylvania.

About 100 people were in the synagogue at the time. It was not known if the baby being circumcised, during a ceremony known as a bris, was harmed.

Bowers, who was in fair condition at a hospital after being shot several times by police, was charged late on Saturday with 29 federal counts, including hate crimes and weapons offences.
