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.

The North Korean Navy has been showing off its new 'Cheo Hyun' class of destroyer, which comes packed with lethal hardware and the ability to fire potentially nuclear-armed ballistic missiles

Kim observed the tests from Nampho Shipyard, where the 5,000-ton destroyer Choe Hyon — launched on Friday — began live-fire drills on Monday, according to the Korean Central News Agency.
