North Korea's Kim 'supervised test-firing of new surface-to-ship missiles'

North Korea says it test-fired new surface-to-ship missiles under the supervision of its leader Kim Jong Un on Wednesday. Kim says there have been frequent intrusions by South Korean naval ships in the Yellow Sea, Report informs via NHK.

The ruling Workers' Party newspaper Rodong Sinmun reported on Thursday that the test-firing of the Padasuri-6 missiles was conducted over waters east of the Korean Peninsula.

The paper says the missiles flew for more than 23 minutes before hitting a target boat.

It also reports that Kim presented a plan to contain an enemy navy by deploying surface-to-sea missiles.

Kim reportedly insisted that a maritime boundary called the Northern Limit Line, or NLL, which was set by UN forces, is groundless "in light of international law or legal justification." He also stressed that his country needs to "thoroughly defend the maritime sovereignty by force of arms and actions."

The article says Kim instructed the country's military to bolster its preparedness in waters north of Yeonpyeong and Baengnyeong islands, which are close to the NLL, saying they are "frequently invaded by the enemies' warships."

North Korea refuses to recognize the NLL, insisting that it is unilateral and invalid. Pyongyang has set its own line south of the NLL. The two Koreas have previously exchanged fire when a North Korean patrol boat crossed the NLL.
