At least one person is dead and two others wounded in a shooting near a polling site in southern California.
The shooting took place in the early afternoon local time in the city of Azusa, 40 kilometers east of Los Angeles, as Americans went to the polls to vote in a presidential election.
Police officers responding to reports of the shooting were greeted by a hail of gunfire. Officers took cover and returned shots at the suspect, who retreated into a home, the Los Angeles Times reported. No police were believed to be injured.
Azusa Police Chief Steve Hunt said officers were searching for at least one female suspect, and possibly a male suspect. Hunt believed the woman was armed with "an assault rifle with rapid-fire capability." Police don't know if the rifle is fully or semi-automatic.
Hunt said a fourth person could be seen lying motionless at the front door of a home, but he couldn't immediately say whether that person was the shooter or another victim.
Officials asked residents to avoid the area. Two polling places and a middle school were placed on lockdown. Elections officials say one of the polling sites later reopened. Voters were being urged to seek nearby polling places.
The motive of the shooting was unknown and it was unclear if it had anything to do with the election.
