North and South Korea just shot at each other.

The engagement ended with no damage being done on the South's side of the border.
While it's not clear what the North's target may have been, some reports have suggested it was trying to hit South Korean loudspeakers playing anti-North propaganda messages.
Those speakers were reactivated last week, after two South Korean soldiers were injured by land mines that the South says the North had planted.
