Singapore has condemned the shootings that took place at Canada's National War Memorial and Parliament Hill.

"Singapore condemns the shootings that took place at the National War Memorial and at Parliament Hill in Ottawa. Our thoughts are with the family of the deceased soldier, the injured victims, as well as the Government and people of Canada during this difficult time," said a Ministry of Foreign Affairs spokesman in response to media queries.

"The attacks underscore the need for countries to remain vigilant in dealing with the threat posed by terrorists. Singapore stands in solidarity with the Canadian Government in the fight against terrorism."

The gunman in the attack on Wednesday has been identified in the Canadian media as 32-year-old Michael Zehaf-Bibeau, who was considered a "high risk" suspect and had seen his passport seized to prevent him fighting abroad.

He shot and killed a Canadian soldier who was mounting a ceremonial guard at a war memorial in downtown Ottawa before storming into the Parliament building.

Video filmed from inside the Parliament building shows officers rushing down a large marble hallway with handguns held in front of them, before the sound of gunfire and shouting rings out.
