The White House said President Barack Obama was “outraged” Tuesday following North Korea’s artillery attack against the South Korean island of Yeonpyeong, the latest in a series of provocations that have reawakened concerns about the threat posed by the communist country and its reclusive leadership.

North Korea fired barrages of artillery onto a South Korean island near their disputed western border Tuesday, setting buildings ablaze and killing at least two marines after warning the South to halt military drills in the area, South Korean officials said.
