In a statement to the press, the Department of Homeland Security says that it doesn't believe the Boston bombings are part of a "broader plot" and it "continues to keep in place enhanced security measures at transportation hubs."
CNN now reports that an 8-year-old child was killed in today's Boston marathon bombings:
"We're now being told, as bad as the situation is, according to ... one of the local stations in Boston, one of the two people killed was an 8-year-old child," said CNN's Wolf Blitzer. "We don't know if it was a boy or girl, but an 8-year-old child killed in this terror attack near the finish line in Boston, at the Boston marathon."
President Barack Obama addressed the Boston Marathon bombing just now from the White House:
The president was careful not to say the bombings were a terrorist attack, but he did say, "We don't yet have all the answers, but we do know that multiple people have been wounded--some gravely--in explosions at the Boston marathon."
