North Korean leader Kim Jong Un supervised a test-fire of a submarine-launched ballistic missile and declared it "the greatest success" that put the country in the "front rank" of nuclear military powers, official media reported on Thursday.
North Korea fired a submarine-launched ballistic missile (SLBM) on Wednesday which flew about 500 km (300 miles). The South Korean government and experts said the launch showed technical progress in the North's SLBM programme.
"A test-fire of strategic submarine-launched ballistic missile was successfully conducted under the guidance of supreme commander of the Korean People's Army (KPA) Kim Jong Un," the North's official KCNA news agency said.
"He appreciated the test-fire as the greatest success and victory," KCNA said.
"He noted with pride that the results of the test-fire proved in actuality that the DPRK joined the front rank of the military powers fully equipped with nuclear attack capability."
