A University of Ottawa security expert has told CBC Radio that today's terrorist attacks in the national capital were organized.
"Clearly this was a plot," Wesley Wark told Anna Maria Tremonti.
He mentioned that as many as three shooters may have been involved. That means there must have been a plan to acquire weapons.
He said that events this week, which also included an ISIS supporter using a motor vehicle to kill a soldier in Quebec, show that authorities will have to "recalibrate" their attention on homegrown terrorism.
"The focus has been recently on the foreign fighter phenomenon," Wark told CBC Radio.
Ottawa remains under lockdown.
This morning just before 7 a.m. Pacific time, a gunman shot a soldier dead outside the National War Memorial.
The attacker reportedly vaulted over a wall and ran toward Parliament Hill.
There were also shots fired inside Parliament Hill in Centre Block before the gunman was shot and killed.
There have also been reports of shooting heard near the Rideau Centre, which isn't far from Parliament Hill. [After this article was posted, the Ottawa Police Service said that contrary to these reports, "no incident occurred near the Rideau Centre."]
CBC Radio has reported that three people have been taken to an Ottawa hospital and two are in stable condition.
The domestic terrorism has occurred after Canada decided to join a U.S.-led coalition conducting air strikes on ISIS targets.
The RCMP is expected to hold a news conference at 10:40 a.m. Pacific time.
