SEOUL -  The leader of the Democratic People's Republic of Koera (DPRK), Kim Jong-un, oversaw a long-range artillery drill on Monday, state media KCNA said on Tuesday.

Analysts said the large MLRS are still a type of ballistic missile, and therefore a potential violation of United Nations Security Council resolutions

The Republic of Korea (ROK) had reported two launches off the east coast into the sea on Monday, but KCNA made no mention of whether missiles were involved.

Photos released by state media showed troops firing a multiple launch rocket system (MLRS), first seen last year and estimated by analysts to be about 400mm-450mm in caliber.

“The men of long-range artillery pieces on the front participating in the drill proudly demonstrated the accurate marksmanship which they had improved in their training,” KCNA reported.

While smaller than some of the other short-range missiles fired by the DPRK last year, analysts said the large MLRS are still a type of ballistic missile, and therefore a potential violation of United Nations Security Council resolutions.

Monday’s launch was the first since the DPRK fired what it called “super-large multiple rocket launchers” on Nov. 28 and follow a year-end deadline the DPRK has put forth for the United States to drop its insistence on unilateral denuclearization by Pyongyang.
