Police in Quebec City have arrested a suspect following a shooting at a mosque there that left six people dead and wounded eight others Sunday night. After initially saying they had two suspects in custody, police said Monday that they determined one of the men was instead a witness.
According to Canadian authorities, a gunman opened fire inside the Quebec City Islamic Cultural Centre around 8 p.m. ET, as about 40 people were gathered for evening prayers.
