Four police officers were shot and killed in a Sunday morning ambush at a Parkland-area coffee shop, officials said.

Emergency personnel rushed to the scene after receiving a report that multiple officers were shot and killed in the ambush at 8:30 a.m. Sunday, according to reports from the scene.

Pierce County Sheriff's Office spokesman Ed Troyer called the ambush "a targeted attack."

KOMO News Radio reported from the scene that a lone gunman burst into the coffee shop, shot the four officers as they were working on their computers, then fled the scene.
