A series of shootings occurred on October 22, 2014, at Parliament Hill in Ottawa. At the Canadian National War Memorial, Michael Zehaf-Bibeau fatally shot Corporal Nathan Cirillo, a Canadian soldier on ceremonial sentry duty. He then entered the nearby Centre Block parliament building, where members of the Parliament of Canada were attending caucuses. After wrestling with a constable at the entrance, Zehaf-Bibeau ran inside and had a shootout with parliament security personnel. He was shot 31 times by six officers and died at the scene. Following the shootings, the downtown core of Ottawa was placed on lockdown while police searched for any potential additional threats. A Royal Canadian Mounted Police (RCMP) investigation into the shootings is ongoing.
