The one-year anniversary of the Pittsburgh synagogue shooting was marked with memorial services around the world.

The attack, on October 27 last year, claimed the lives of 11 worshippers at the Tree of Life – Or L’Simcha synagogue in the city’s Squirrel Hill neighbourhood.

It was the deadliest antisemitic attack in US history.

A steady stream of people attended the shul on Sunday, leaving flowers and tributes to the victims.

Tom Wolf, the Governor of Pennsylvania, said: “Today, we remember those lost and come together as a commonwealth to stand united as neighbours.”

A minute’s silence will be held during the Pittsburgh Steerlers’ Monday night game against the Miami Dolphins.

A public commemoration ceremony also took place at Pittsburgh’s Soldiers and Sailors Memorial Hall, where a vigil was held a day after the attack.

Jewish leaders chose the theme of “Remember, Repair, Together” for Sunday’s services, which also included community service projects and study sessions of the Torah.

Robert Bowers, 47, has been charged with 29 criminal counts, including use of a firearm to commit murder. Prosecutors are understood to be seeking the death penalty.
