Children are among the fatalities in a mass shooting at a child's birthday party in California.
Police said four people had died and 10 were wounded in the incident in Stockton, about 60 miles east of San Francisco.
Officers were called on Saturday to a banquet hall just before 6pm local time (2am UK time) and district attorney Ron Freitas said children were among the dead.
He said the attacker was still at large.
"We can confirm at this time that approximately 14 individuals were struck by gunfire, and four victims have been confirmed deceased," San Joaquin County Sheriff's Office said on X.
The post said early indications suggest it could be a "targeted incident" but that information remains limited.
Police have so far not disclosed the attacker's identity and the motive is unclear.
Stockton's vice mayor Jason Lee confirmed on Facebook that the shooting on Lucile Avenue happened at a child's birthday party.
Mayor Christina Fugazzi said that "families should be together instead of at the hospital, standing next to their loved one, praying that they survive".
California governor Gavin Newsom's office added that he had been briefed on the "horrific shooting".
