FROM THE CBC: Ottawa Parliament Hill Shootings; Live Updates.

UPDATE: Looks like Islamic terrorism: “Canada’s government is tracking today’s violence as a terrorist incident, and will reportedly continue treating it as such until evidence suggesting that it is not terrorism comes to light. That is in sharp contrast to how the Obama administration handles suspected terrorist attacks in the US. The FBI and other government agencies in the US default to something other than terrorism first, and still considers Nidal Hasan’s 2009 terrorist attack at Fort Hoot, Texas an incident of ‘workplace violence.'”

But stay tuned. Early reports are often unreliable.
