South Korea warns North Korea after artillery barrage

SEOUL, South Korea — South Korea denounced a barrage of artillery fired by North Korea into the sea as a grave provocation Tuesday and warned that it would deal sternly with any further such acts.
North Korea fired about 110 rounds Monday near its disputed western sea border with South Korea, shortly after Seoul ended five-day naval drills staged in response to the March sinking of its Cheonan warship. North Korea has been blamed for the vessel's destruction, which killed 46 sailors.
The North denies it torpedoed the Cheonan and has warned any punishment would trigger war.
