SEOUL, South Korea (AP) - South Korea officials are trying to determine out what exactly North Korea fired into its eastern waters over the weekend.
A Defense Ministry official speaking on condition of anonymity citing department rules says experts are analyzing whether the projectiles are short-range missiles or a new type of artillery the country may be developing.
North Korea fired what Seoul officials called a short-range projectile Sunday, a day after conducting three similar launches.
A Defense Ministry spokesman says South Korea is taking seriously whatever weapons the North develops because it could attack the South. He said an artillery gun with a bigger caliber will likely have more destructive power.
North Korea routinely test-launches short-range missiles. But the latest launches came amid some tentative signs of easing tension on the Korean Peninsula.
