U.S. President Barack Obama on Wednesday offered his condolences to Canadian Prime Minister Stephen Harper over the "tragic" attack near parliament and pledged continued security coordination with Ottawa, Agence France-Presse reported.
"Obviously, the situation there is tragic," Obama told reporters in the Oval Office after Wednesday's attack.
"Just two days ago, a Canadian soldier had been killed in an attack. We now know that another young man was killed today, and I expressed, on behalf of the American people, our condolences to the family and to the Canadian people as a whole," he said after speaking with Harper by telephone.
"We don't yet have all the information about whether this was part a broader network or plan, or whether this was an individual or a series of individuals who have decided to take these actions," Obama said.
He pledged to ensure that U.S. and Canadian "national security teams are coordinating very closely," especially given their long common border.
Fight against terrorism
"We are also reminded that attacks on our security personnel and on our institutions of governance are by their very nature, attacks on our country, on our values, on our society, on us Canadians as a free and democratic people who embrace human dignity for all," he said.
Harper also told Canadians more would come out "about the terrorist and any accomplices he may have had."
