North Korea Building at Nuclear Site for First Time Since 2018

  • Punggye-ri site has been used for its six nuclear tests
  • Kim Jong Un has opened 2022 with barrage of missile launches

North Korea is undertaking construction work at its main nuclear weapons test site for the first time in about four years, according to an analysis of satellite imagery, raising fresh security concerns as South Korea elects a new leader.

Images captured Friday show “very early signs” of activity at the mountainous area of Punggye-ri, including the construction of a new building and repairs to another structure, weapons expert Jeffrey Lewis wrote on his Arms Control Wonk website. “North Korea uses a substantial amount of wood at the site both for buildings and shoring up tunnels.  These changes have occurred only in the past few days,” Lewis wrote Monday.
