1. Canada shootings. Canadian police are investigating three shootings that occurred across Ottawa. The first took place at the National War Memorial, where the gunman killed a soldier. The other shootings occurred near the Rideau Centre and inside the Canadian Parliament building, which is on lockdown. The gunman who opened fire in Parliament was shot dead by the legislature's Sergeant-at-Arms, Kevin Vickers. Assistant Police Commissioner Gilles Michaud described the incidents as a "dynamic and unfolding situation" and urged Canadians to be vigilant and report any suspicious activity to police. Today's attacks come just three days after a man who Canadian authorities say was "radicalized" was shot to death in Quebec after hitting two Canadian soldiers with his car, killing one of them.
