OTTAWA, Canada—A gunman with a scarf over his face shot to death a Canadian soldier standing guard at the nation’s war memorial Wednesday, then stormed Parliament in a hail of gunfire before he was killed by the usually ceremonial sergeant-at-arms, authorities and witnesses said.
The attack immediately raised the specter of terrorism, with Canada already on heightened 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.
