A gunman shot and killed a soldier who was standing guard at the Canadian War Memorial in Ottawa on Wednesday, Oct. 22.

The gunman then went to Parliament Hill, where he was reportedly killed after trading shots with Parliament’s sergeant-at-arms.

Multiple shots were fired within the halls of the Parliament building.

Prime Minister Stephen Harper was safely removed from Parliament Hill, and his events for the day cancelled. Liberal leader Justin Trudeau and NDP leader Thomas Mulcair were also reported safe.

MPs were locked down inside the buildings as police searched for any other gunmen involved in the attack.

The attack on Parliament Hill took place two days after two soldiers in Quebec were intentionally run down in a car driven by 25-year-old Martin Couture-Rouleau, who was one of 90 suspected extremists being watched by the RCMP.

Couture-Rouleau led police on a chase and was shot and killed when he emerged from his crashed vehicle with a knife in his hand.

The attack on Parliament Hill occurred just before 7 a.m. local time.

At the B.C. legislature on Wednesday, extra guards were stationed at each entrance. Tourists and members of the public were prohibited from entering, but pre-booked school tours were allowed to enter the building.

The situation in Ottawa was ongoing as of the Herald’s press deadline.
