Portland car packed with explosives crashes into MAC; officials call it isolated

A man drove a car packed with explosives and propane into Portland's Multnomah Athletic Club early Saturday, killing himself and igniting a fire; investigators found multiple incendiary devices, some partially detonated, and bomb-disposal robots were deployed as authorities cleared the scene. Police described the incident as isolated and not an act of domestic terrorism; the MAC remains closed indefinitely while investigators identify the driver and determine a motive.
