A gunman has shot & killed four police officers, at a coffee house in the US state of Washington. Three men and one woman were killed in the attack about 50 kilometers southwest of Seattle.

The officers were catching up on paperwork at the beginning of their shifts, when the attack happened Sunday morning.
