Kim expresses satisfaction on tests:

North Korea said Saturday that leader Kim Jong Un supervised another test-firing of an unspecified new weapon, seen as an attempt to pressure Washington and Seoul over slow nuclear negotiations and their joint military exercises.

Pyongyang’s Korean Central News Agency, or KCNA, said that following Friday’s launches, Kim expressed “great satisfaction” over his military’s “mysterious and amazing success rates” in recent testing activity and vowed to build up “invincible military capabilities no one dare provoke.” The report did not mention any specific comment about the United States or South Korea.

The launches were North Korea’s sixth round of tests since late July that revealed developments of a new rocket artillery system and two separate short-range mobile ballistic missile systems that experts say would expand its ability to strike targets throughout South Korea, including US bases there.

KCNA did not describe what Friday’s weapons were or how they performed, but said that the tests were successful and strengthened the military’s confidence in the reliability of the system.

North Korea’s official Rodong Sinmun newspaper published photos that showed what appeared to be a missile soaring from a launcher installed on a vehicle and striking what appeared to be a coastal target. Kim is seen jubilantly raising his fist while celebrating with military officials. (AP)
