Video footage has emerged of the moment shots were fired inside the Canadian parliament building following the shooting of a soldier in Ottawa.

At least one gunman has been shot dead and the parliament building was put under lockdown following the incident this afternoon.

A Canadian soldier was shot at the National War Memorial in Ottawa, police have said, while witnesses have described seeing a man armed with a long rifle chased by police into the nearby Parliament building.

Footage from inside parliament, captured by a reporter for The Globe and Mail, shows the moment shots were fired as police made their way through the building.

Canadian Prime Minister Stephen Harper was reported to have been evacuated from the building, while police warned members of the public to stay away from windows and roofs.

John Ivison, an Ottawa-based political correspondent, said police believed there were "multiple assailants" and that the area was still "not secure".

The incident comes just two days after two Canadian soldiers were run over — and one of them killed — in Quebec by a man suspected to be an Islamist extremist.
