SEOUL   -    North Korea’s test of a new missile is meant as a “solemn warning” over rival South Korea’s weapons development and plans to hold military drills with the United States, Pyongyang said Friday as it continued its pressure campaign ahead of potential nuclear talks.  South Korea’s military later said that the flight data of the weapon launched Thursday showed similarities to the Russian-made Iskander, a short-range, nuclear-capable missile. A North Korean version could likely reach all of South Korea — and the 28,500 US forces stationed there — and would be extremely hard to intercept. The North Korean statement was carried in state media and directed at “South Korean military warmongers.” It appears to be part of broader efforts during recent weeks to make sure Pyongyang gets what it wants as US and North Korean officials struggle to set up working-level talks after a recent meeting.
