Groups of gunmen attacked two separate parties during the night in the Los Angeles area, killing two teenagers and wounding at least nine other people, authorities said on Sunday.
There were no immediate arrests in either shooting, police said. The first shooting happened late yesterday in Long Beach, where several gang members apparently crashed a birthday party and started a fight, police Sgt Dina Zapalski said.
A 17-year-old boy and a 15-year-old girl died of gunshot wounds, Zapalski said. Another 17-year-old boy suffered injuries that were not life-threatening.
Early on Sunday, four or five men turned up at a party in Compton and opened fire, Los Angeles County Sheriff's Deputy Tony Moore said.
Eight people were wounded in the Compton shooting, three of them critically, authorities said.
