President Barack Obama called the Boston bombings an “act of terror” on Tuesday, but said it was still unclear if a foreign or domestic group or individual was behind the attacks.
In an appearance in the White House briefing room, Obama urged Americans to be vigilant and to watch for suspicious activity a day after two explosions rocked the finish line of the Boston Marathon, killing at least three people and wounding scores more.
“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.”
The FBI’s investigation into the bombings was in full swing Tuesday, with authorities serving a warrant on a suburban Boston home and appealing for any private video, audio and still images of the blasts.
Officials said no one had claimed responsibility for the bombings that left the streets splattered with blood and glass on one of the city’s most famous civic holidays, Patriots Day.
