Police say at least nine people were injured at a Philadelphia cookout when they were hit by birdshot from a shotgun, and two men are being sought.

Witnesses told police that the suspects fired down a block in West Philadelphia's Belmont neighborhood with a shotgun at least once shortly before 10 p.m. Saturday. Police say the pair then drove down the street in a sedan, firing several more shots, possibly with a handgun.

Police say the victims are a 1-year-old girl and two boys, ages 11 and 12, as well as four men and two women. A police spokeswoman says all were taken to hospitals and listed in stable condition.

One suspect is described as in his 20s with a beard and tattoos on one arm.
