Parliament Hill attack: 1 gunman dead after soldier shot at National War Memorial
Parliament Hill came under attack today after a man with a rifle shot 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.
MPs and other witnesses reported several shots fired inside Parliament, and a gunman has been confirmed dead inside the building, shot by the House of Commons Sergeant-at-Arms, according to MPs' eyewitness accounts.
The soldier's condition is not known as this time.
The prime minister was on the Hill at the time of the shooting, but was safely take away. It's believed one suspect is still at large.
This happened three hours ago so there are not a lot of facts available.
