Police: No Motive Cited in Deadly Ottawa Attack

Police aren't speculating on a motive for today's shooting attack in the Canadian capital of Ottawa. Police have identified the gunman as Michael Zehaf-Bibeau.

A Canadian soldier who had been standing guard at a war memorial was shot to death by a man who witnesses say then entered the nearby Parliament building, where gunfire then rang out.

Police say they are hunting for as many as two other shooters.

Police are giving no details on how the gunman died. But on Twitter, a member of Parliament credited the legislature's sergeant-at-arms, Kevin Vickers, with shooting the attacker just outside the lawmakers' caucus rooms.

The U.S. Embassy in Ottawa was locked down as a precaution. And security was tightened at the Tomb of the Unknown Soldier at Arlington National Cemetery outside Washington.

Canada had already been on alert after a deadly hit-and-run attack earlier in the week against two Canadian soldiers by a man who police say was a recent convert to Islam and had been radicalized.

President Barack Obama has condemned fatal shootings in Canada as "outrageous attacks" and has offered to help the U.S. ally with its response.

The White House says Obama spoke by telephone Wednesday with Prime Minister Stephen Harper.

A Canadian soldier standing guard at a war memorial in the capital of Ottawa, Ontario, was shot and killed Wednesday. Gunfire also erupted inside Parliament and authorities say at least one gunman was killed.

On Monday, authorities say a recent convert to Islam killed one Canadian soldier before being shot to death by police.

Obama also expressed the American people's solidarity with Canada.

The Homeland Security Department says there is no specific threat to the U.S. amid the ongoing shooting incident in Ottawa, Ontario.

The department said Wednesday that it is continuing to monitor the situation in the Canadian capital, and U.S. security efforts will be changed as necessary.

Meanwhile, the NHL has postponed Wednesday night's game between the Toronto Maple Leafs and Senators because of shootings in Ottawa.

In a statement the NHL says it "wishes to express its sympathy and prayers to all affected by the tragic events in Ottawa."

The game was scheduled at the Canadian Tire Centre in nearby Kanata.

The NHL says the date and time of the rescheduled game will be announced at a later date.  (AP)
