US President Barack Obama on Tuesday branded the Boston bombings a "cowardly" act of terror, but said it was still unclear if a foreign or domestic group or individual was behind the attacks.
"This was a heinous and cowardly act," Obama said at the White House. "Any time bombs are used to target innocent civilians, it is an act of terror."
Obama said while the impact of the attacks near the finish line of the Boston marathon on Monday, which killed three people and wounded more than 170 others, were clear, the motives and the identify of those responsible was not.
