Bomb found on MLK march route; FBI suspects domestic terrorism

SPOKANE, Wash. — A backpack found along the route of the Martin Luther King Jr. march in Spokane contained a bomb "capable of inflicting multiple casualties," the FBI said Tuesday, describing the case as "domestic terrorism."

The FBI said the Swiss Army-brand backpack was found about 9:25 a.m. PST on Monday on a bench at the northeast corner of North Washington Street and West Main Avenue in downtown Spokane.

In an interview on msnbc cable's "The Rachel Maddow Show," Spokesman-Review reporter Thomas Clouse said confidential sources told him that the device was equipped with a remote control detonator and contained shrapnel.

A bomb disposal unit was called in and neutralized the device with a robot. The FBI said in a statement on Tuesday that "the backpack contained a potentially deadly destructive device, likely capable of inflicting multiple casualties."

The FBI has refused to discuss how the bomb was constructed.
