The Canadian capital, Ottawa, went into lockdown Wednesday after a shooter opened fire at the National War Memorial. The gunman shot and killed Corporal Nathan Cirillo, who was guarding the tomb of the unknown soldier, then entered the nearby Parliament, where he was shot dead. The gunman was identified as Michael Zehaf-Bibeau, a convert to Islam with a history of drug and robbery offenses. The attack came two days after a man identified as a “radicalized” Muslim convert drove a car into two Canadian soldiers, killing one of them. The incidents have sparked fears of blowback after Canada joined the U.S.-led war against Islamic State militants in Iraq and Syria. Canadian Prime Minister Stephen Harper addressed the nation.

Canadian Prime Minister Stephen Harper: “Canada will never be intimidated. In fact, this will lead us to strengthen our resolve and redouble our efforts, and those of our national security agencies, to take all necessary steps to identify and counter threats and keep Canada safe here at home, just as it will lead us to strengthen our resolve and redouble our efforts to work with our allies around the world and fight against the terrorist organizations who brutalize those in other countries with a hope of bringing their savagery to our shores.”
