NEW YORK (PIX11) - The NYPD raised police presence at locations affiliated with the Canadian government after at least one man opened fire Wednesday morning, killing a soldier.

Police from the Hercules Team wearing body armor and carrying automatic rifles patrolled the exterior of the Canadian Consulate in Times Square, and the British Consulate in Midtown East.

The NYPD "Special Attention" response followed a bloody attack in Ottawa at the Canada War Memorial that killed a reservist from Hamilton Ontario named Cpl. Nathan Cirillo.

The gunman then entered the nearby Parliament building before he was shoot and killed, according to Ottawa police. It's still unclear exactly what transpired inside the building, but a reporter for the Globe and Mail recorded a chilling burst of gunfire from either the suspect, police or both.

The shooter, identified by a Canadian official as Michael Zehaf-Bibeau, was shot and killed, but police are still trying to rule out the possibility of multiple shooters.

President Obama spoke addressed reporters, and is urging the public to stay vigilant, saying, "We don't yet have all the information about what motivated the shooting. We don't yet have all the information about whether this was part of a broader network, or plan, or whether this was an individual, or series of individuals, who decided to take these actions."
