Michael Zehaf-Bibeau has been identified as the shooting suspect at Parliament Hill in Ottawa, Canada on Wednesday. One soldier who was shot and rushed to hospital later died of his injuries while three other shooting victims remain in hospital. 

Earlier this morning, Zehaf-Bibeau shot a soldier at the national War Memorial before entering the Centre Block. More shots were heard, according to witneses, before he was shot dead.

Zehaf-Bibeau is a Canadian native born in 1982. So far, no motive has been linked to the attack. 

Canadian police are investigating Michael Zehaf-Bibeau after two U.S. officials said that U.S. agencies have been advised that the shooter was a Canadian convert to Islam. One of the officials said that the man was from Quebec.

The gunman was reportedly dressed in all black and had a scarf over his face. 

It has not been confirmed whether the gunman was alone or was with accomplices at the time of the attack.

The incident has shocked Canada, and Parliament and buildings in downtown remained on lockdown. 

Prime Minister Stephen Harper said that government and parliament should continue its work, according to a spokesman. "While the prime minister stated that facts are still being gathered, he condemned this despicable attack," the spokesman said.

Police stated that an operation was under way to make parliament safe and they were still in the middle of an active investigation.

"It caught us by surprise... If we had known that this was coming, we would have been able to disrupt it," Gilles Michaud, assistant commissioner of the Royal Canadian Mounted Police, (RCMP) told a news conference.
