Four police officers have been shot dead in an ambush at a coffee shop in Washington State, police say.
Officials quoted by local media said two gunmen had walked into the coffee shop in Parkland, near the McChord Air Force Base, and opened fire.
A sheriff's spokesman said the officers had been targeted and it was not believed to have been a robbery.
Other customers were in the coffee shop at the time but no-one else was injured, KOMO-TV reported.
Parkland is in Pierce County, 40 miles south of Seattle.
Pierce County Sheriff's spokesman Ed Troyer told local media that the officers had been working on their laptops in the coffee shop when the shooting happened on Sunday morning.
