Pittsburgh synagogue attack: Suspect in custody

Three officers were also shot in the attack at the Tree of Life Synagogue in Pittsburgh's Squirrel Hill neighbourhood.

Police are reporting a suspect is in custody after a shooting that caused "multiple casualties" at a Pittsburgh synagogue on Saturday.

Three officers were also shot in the attack at the Tree of Life Synagogue in Pittsburgh's Squirrel Hill neighbourhood.

Police spokesman Chris Togneri says police have no more information at this time because they are still trying to clear the building and figure out if any more threats exist.

The synagogue is located at the intersection of Wilkins and Shady avenues. The tree-lined residential neighbourhood of Squirrel Hill, about 10 minutes from downtown Pittsburgh, is the hub of Pittsburgh's Jewish community.

President Donald Trump says he's been monitoring the shooting. In a tweet, Trump encouraged people to shelter in place and said: "looks like multiple fatalities."
