Manhunt continues as police chase 'suspect from Russia'

The two suspects in the Boston Marathon bombing were from the Russian region near Chechnya, sources have told the Associated Press, as a massive police manhunt continues for the surviving suspect.

One of the two men died in a shootout with police after the suspects shot dead an MIT police officer, injured a transit officer in a firefight and threw explosive devices at police during their getaway attempt in a long night of violence.
