A Canadian man who rammed two soldiers in Quebec with his car, killing one of them, converted to Islam last year and was among 90 people being tracked by Canadian police on suspicion of taking part in militant activities abroad or planning to do so.
Monday's incident, the first fatal attack on Canadian soil tied to Islamic militants, occurred after Canada announced this month it was joining the battle against Islamic State fighters who have taken over parts of Iraq and Syria.
Royal Canadian Mounted Police (RCMP) Commissioner Bob Paulson said on Tuesday that the attacker was one of 90 individuals the force has been investigating. The RCMP had previously seized his passport because it feared he might try to go abroad, Paulson said.
