Police responding to an active shooter call at a Pittsburgh synagogue were met almost instantly by a hail of automatic gunfire from a suspect firing an AR-15 rifle.

Dramatic radio transmissions recorded by Broadcastify, show the first call to police was from the Tree of Life Synagogue, reporting an active shooter. “The complainant says they have an active shooter in the building, a second call says they are being attacked.”

Police received calls from people inside the synagogue, “Okay, multiple gunshots are heard from the lobby, possibly 20-30 shots.” “There are several people hiding.”

Police were fired on as soon as they got to the scene, “We’re under fire, we’re under fire, he’s got an automatic weapon, he’s firing out of the front of the synagogue.”
