North Korea plans to dismantle nuclear test site

North Korea said Saturday it will dismantle its nuclear test site between May 23 and 25, in a dramatic event that would set up leader Kim Jong Un's summit with President Donald Trump next month.

The announcement, by the Ministry of Foreign Affairs as reported by state news agency KCNA, came a day after Pyongyang pledged no longer to carry out unannounced missile tests or other activities that put flights at risk, according to a United Nations aviation agency.

North Korean leader Kim Jong Un previously had announced the conclusion of North Korea's nuclear testing program and the intended shuttering of the Punggye-ri complex. He said on April 20 that his nation already had "completed its mission" to test its weapons capability.

The statement Saturday gave greater details of the "technical measures" North Korea would take to dismantle the test site and "ensure transparency of discontinuance of the nuclear test."
