A former US soldier has been sentenced to 32 years in prison for planting a bomb along the route of the Martin Luther King Day parade in Washington state in January.
Kevin Harpham used a pipe bomb loaded with fishing weights covered in rat poison, but it was disabled before it could explode. A guilty plea was entered in September.
Harpham, 37, was arrested at his home on 9 March.
The backpack bomb was discovered on a bench in downtown Spokane on 17 January by three city employees about 30 minutes before the parade was scheduled to begin.
The parade was rerouted while a bomb disposal unit was summoned to neutralize the device.
The FBI said the bomb was capable of causing serious injury or death if it had exploded.
