N.Korea Resumes Tests for Smaller Missile Warheads

      February 26, 2015 12:13

      North Korea has resumed high-explosive tests believed to be aimed at making smaller and more powerful warheads for ballistic missiles, a government source said Wednesday.

      The North conducted no fewer than 139 high-explosive tests between the early 1980s until 2002.

      Intelligence officials here believe North Korea's next nuclear test will produce a yield of at least 10 to 15 kilotons. That would be similar in power to the atomic bomb that was dropped on Hiroshima at the end of World War II.

      The last nuclear test in 2013 produced an estimated yield of 6 to 7 kilotons.

      But the government source added there are no signs that the North is preparing for a nuclear test at the site in Punggye-ri, North Hamgyong Province.
