One soldier died and another was injured when a 25-year-old Islamic “radical” allegedly ran them down in a Quebec parking lot. The suspect, Martin Rouleau, gave chase and flipped his car before being fatally shot by police. Rouleau had increasingly radicalized after converting to Islam last year. Was he acting on behalf of ISIS, which has encouraged attacks in Western countries? That remains unclear, but he was on national security’s radar, and authorities had reportedly seized his passport.
