Gunmen killed six people and wounded eight others at a Quebec City mosque in what Canadian Prime Minister Justin Trudeau called a “terrorist attack on Muslims” and the religious tolerance “that we, as Canadians, hold dear.” One suspect was arrested at the mosque, the Islamic Cultural Center of Quebec. Another suspect was arrested nearby in d’Orleans, Quebec. Canadian news outlets reported the suspects have been identified as Alexandre Bissonnette and Mohamed Khadir, two men in their “late 20s and early 30s” who were “not known to police,” Montreal Gazette wrote. Police did not immediately identify what investigators thought had motivated the attack. Mass shootings are rare in Canada, which has welcomed refugees fleeing war and terrorism in Syria and other predominantly Muslim nations.
