Six people have been killed and a further 12 people injured in a mass shooting event in the Californian city of Sacramento involving multiple shooters, police say.
Shots rang out on Sunday morning (local time) as people filed out of bars and nightclubs, in what is simply the latest mass casualty shooting in the country plagued by gun violence.
A video posted to Twitter showed people running through the street amid the sounds of rapid gunfire.
Separate footage appears to show a brawl outside a bar as people were filmed in a violent altercation, which reportedly took place moments before the shooting. Authorities are reviewing the video in which shots can also be heard.
Shots were fired into crowds as bars and nightclubs emptied for the night in the second mass shooting in five weeks in California's capital city.
Police in a statement said it's not yet clear if the fight was related to the shooting.
Police Chief Kathy Lester told reporters that three of the victims who died in the shooting were women and three were men. She said all were adults.
The suspects were still at large on Sunday night in the US and authorities said they had recovered at least one firearm.
The crime scene stretched across several city blocks, with dozens of blue and yellow evidence markers dotting the pavement. Several victims battled life-threatening gunshot injuries in hospitals.
Witnesses saw gunman running while opening fire
Speaking to the Associated Press, witness Kelsey Schar said she heard gunshots and saw flashes in the dark. She walked to the window and "saw a guy running and just shooting".
Her friend, Madalyn Woodard, said she saw a crowd in the street scatter amid the gunfire and a girl who appeared to have been shot in the arm laying on the ground.
"This morning our city has a broken heart," Sacramento Mayor Darrell Steinberg said. "We don't know all the facts but we know there were mass casualties in a very short amount of time."
Sunday's violence was the third time in the US this year that at least six people have been killed in a mass shooting, according to a database compiled by The Associated Press, USA Today and Northeastern University.
