Four people have died after 10 were shot at a party in California.
The shooting happened at around 6pm local time, in the city of Fresno, as people gathered in a garden to watch an American football game.
Deputy Chief Michael Reid told the Fresno Bee and the KSEE/KGPE TV stations that three people were found dead at the scene while a fourth victim died at the hospital.
The six other victims are expected to survive and are recovering at the hospital, police said.
"What we do know is that this was a gathering, a family and friend gathering in the backyard," Fresno Police Lt. Bill Dooley said. "Everyone was watching football this evening when unknown suspects approached the residence, snuck into the backyard and opened fire."
Others were taken to Community Regional Medical Centre.
Reports said they were either in critical or in critical but stable conditions.
Police do not have suspects in custody, according to reports,
Agents from the US Bureau of Alcohol, Tobacco, Firearms and Explosives field office in San Francisco are responding to the shooting, the Bee reported.
It was at least the second fatal gun attack Sunday in southeast Fresno, the Bee reported, after a man in his 20s was shot to death early Sunday at a home in another part of the city.
Police have not said whether the incidents could be connected.
