North and South Korea OPEN FIRE as they blast warning shots at sea border

NORTH and South Korea have opened fire with warning shots and artillery rockets amid boiling tensions between the two states.

An earlier clash between the two at their disputed maritime border caused North Korea to fire ten artillery rockets off its west coast early on Monday.

South Korean military had fired warning shots at a North Korean boat that crossed the two Koreas' maritime border at 3.50 am, North Korea's official KCNA said.
