Canada Shooting: Police Hunt More Gunmen

The public are told to stay away from roofs and windows after reported shootings at several locations in Ottawa, including a mall.

Ottawa is in lockdown as police search for up to three gunmen after one was reportedly shot dead inside Canada's parliament building.

Police told the AFP news agency that possibly up to three shooters were feared to be on the roof of the building in the capital.

It came after a soldier guarding the nearby National War Memorial was shot and killed, according to an official.

Shots were also fired near the Rideau Centre Mall less than a mile away, police said.

Armed forces bases across the country are being closed to the public in the aftermath of the shooting, CBC TV reported.
