North Korea pledges to destroy its nuclear test site

North Korea has planned to destroy its nuclear test site, Punggye-ri. This decision comes ahead of a summit with the United States. North Korea has pledged to blow up its tunnels in front of invited foreign media. North Korea's announcement to destroy its test sites has largely been triggered by the upcoming Winter Olympics in the South. Pyongyang's nuclear and ballistic missile programmes were subjected to strict sanctions by the UN Security Council, the US, EU, South Korea and others. Therefore, tensions were mounting for years.
