North Korean leader Kim Jong Un on Saturday guided the test-launch of a new weapon which has “superior tactical character” compared to existing weapons systems, the country’s state media reported on Sunday.

Scientists in the field of national defense science and workers in the field of the munitions industry “completed another new weapons system and made a proud report to the Party Central Committee,” Korean Central News Agency (KCNA) and the party daily Rodong Sinmun reported in a Korean-language report.
