At the moment Canada's police cannot confirm that fire at the National War Memorial and at the Canadian Parliament in Ottawa was opened by the same person, RIA Novosti reported referring to a police representative.
According to the Royal Canadian Mounted Police, an investigation has been launched to identify a number of suspected individuals.
On Wednesday morning, a soldier, who was standing guard at the National War Memorial in Ottawa, was shot by an unidentified gunman. Shortly after, shots were fired at the Canadian Parliament, which is located nearby.
One suspected attacker has been shot and killed, the police informed, refraining from commenting on whether the killed gunman was a Canadian citizen.
Ottawa residents have been advised to avoid going to the shooting sites and to "stay away from windows and off roofs" in downtown Ottawa.
The incidents came just two days after a member of the Canadian Armed Forces was killed in a car attack in the city of Saint-Jean-sur-Richelieu in Quebec. Canada's Minister of Public Safety and Emergency Preparedness Steven Blaney said Tuesday that the attack is linked to terrorism.
