SEOUL, South Korea (AP) — North Korea said Wednesday leader Kim Jong Un observed the test-firings of missiles from a recently launched destroyer — the first such warship for the North — and called for accelerating efforts to boost his navy’s nuclear attack capabilities.

SEOUL (Reuters) -North Korea earlier this week conducted the first test-firing of the weapons system of the new "Choe Hyon-class" warship it recently unveiled, state media KCNA reported on Wednesday.

North Korean leader Kim Jong Un reportedly oversaw the test of a supersonic cruise missile fired from a new battleship -- the destroyer Choe Hyon -- this week.
