A day after a gunman killed an army reservist in the Canadian capital of Ottawa, many questions remain, says CNN. Why did he shoot? Why did he target Nathan Cirillo? Is he connected to the militant group ISIS? The attack at parliament yesterday that killed Cirillo was the second this week. On Monday, a man Canadian authorities said was “radicalized” hit two soldiers with a car in Quebec, killing one of them. Police later killed the man. The U.S. tightened security at its Embassy in Ottawa and another consulate in the country after jihadist chatter indicated an attack could be in the works.
The shooter was born Michael Joseph Hall in Canada in 1982. Authorities said he changed his name to Michael Zehaf-Bibeau. His attack came two days after a “radicalized” man killed a soldier with his car, and five days after Canada raised its threat level. Sources told CNN that he converted to Islam. Ottawa Mayor Jim Watson said the gunman was acting alone. “It appears there was just one shooter, and that shooter is dead,” he said. It’s not known why the gunman shot Cirillo in the back “in cold blood” while he stood guard at Canada’s National War Memorial.
