CBC's Dean Beeby has a complete article up on today's tragic events in Ottawa.
Parliament Hill came under attack today after a man with a rifle shot and fatally wounded a soldier standing guard at the National War Memorial in downtown Ottawa, before seizing a car and driving to the doors of Parliament Hill's Centre Block nearby.
The slain soldier is Cpl. Nathan Cirillo, 24, a reservist from Hamilton.
Moments later, MPs and other witnesses reported 30 to 50 shots fired inside the main Parliament building.
It was confirmed later the gunman was shot dead inside the building, felled by the House of Commons sergeant-at-arms and RCMP, according to MPs' accounts.
Prime Minister Stephen Harper was on the Hill at the time of the shooting, but was safely taken away. Harper is expected to make an address to the country later this evening.
CBC News has confirmed the dead shooting suspect is Michael Zehaf-Bibeau, a Canadian born in 1982. CBC News has learned that Zehaf-Bibeau has a criminal record in Quebec dating back 10 years on some drug-related charges. Court documents from that time show that he lived at an address in Montreal.
