SAN FRANCISCO - At least 10 people were wounded in an exchange of shooting at a car show in Kent, 32 km south of Seattle, police said.

KOMO-TV quoted police sources as saying that the fight started when a man criticized another car owner's paint job and the quarrel later turned into a brawl between two groups. At some point, someone pulled out a gun and started shooting.

Ten people have been hospitalized, all with non-life-threatening injuries, the Seattle Times said.

It is still unclear how many shooters were involved, but the shooting may have been gang-related, according to the police.
