OTTAWA, Ontario (AP) — A gunman shot and wounded a Canadian soldier standing guard at a war memorial in Ottawa on Wednesday, then entered Parliament, where numerous shots rang out, police and witnesses said.

People fled Parliament by scrambling down scaffolding erected for renovations, witnesses told the Canadian Press news agency. Others were in lockdown.

Ottawa police Constable Marc Soucy said it was unclear whether there was more than one shooter.

The attack came two days after a recent convert to Islam killed one Canadian soldier and injured another in a hit-and-run before being shot to death by police. The killer had been on the radar of federal investigators, who feared he had jihadist ambitions and seized his passport when he tried to travel to Turkey.

On Wednesday, video taken by a reporter for the Globe and Mail showed police officers walking slowly through Parliament toward the entrance with guns drawn. The sound of a gunshot ran out, followed by the sounds of multiple shots.

The top spokesman for Prime Minister Stephen Harper said Harper was safe and had left Parliament Hill.

Soucy said shots were also fired at a shopping mall near Parliament. All three sites — the National War Memorial, Parliament and the mall — are within less than a mile from each other.

"Most of downtown Ottawa is in lockdown," Soucy said.

Cabinet minister Tony Clement tweeted that at least 30 shots were heard inside Parliament, where Conservative and Liberal MPs were holding their weekly caucus meetings.

"I'm safe locked in a office awaiting security," Kyle Seeback, another member of Parliament, tweeted.

Royal Canadian Mounted Police warned people in downtown Ottawa to stay away from windows and rooftops.

The wounded soldier was taken away in an ambulance. His condition was not immediately known.
