Hagel: Boston Bombing 'Cruel Act of Terror' "Like all Americans the thoughts and prayers of our people at DoD and all of Washington are with the people today, especially the families of the victims and those injured by what appears to be a cruel act of terror. As the President said yesterday we still do not know who did this or why. A thorough investigation will have to determine whether it was carried out by a terrorist group -- foreign or domestic. It's important not to jump to conclusions before we have all the facts. But as the White House said last night, any event with multiple explosive devices, as this appears to be, is clearly an act of terror and will be approached as an act of terror."
