Police search cars and pedestrians as they leave the Alexandra Bridge and enter Gatineau, Quebec near the Parliament Buildings in Ottawa on Wednesday, Oct. 22, 2014. A Canadian soldier standing guard at a war memorial in the country's capital was shot to death and heavy gunfire then erupted inside Parliament. One gunman was killed, and police said they were hunting for as many as two others. The attack immediately raised the specter of terrorism, with Canada already on alert because of a deadly hit-and-run earlier in the week against two Canadian soldiers by a man who police say was fired up with radical Muslim fervor.
