Watch North Korea destroy Punggye-ri nuclear testing site (VIDEO)
The three operational tunnels at the site were demolished along with the accompanying structures, according to the RT correspondent Igor Zhdanov, invited to witness the event.
North Korea had conducted six nuclear tests at the site. The demolition was meant to demonstrate Pyongyang’s commitment to denuclearization after the April summit between Kim Jong-un and South Korean President Moon Jae-in in the demilitarized zone separating the divided peninsula.
Just hours after the demolition, US President Donald Trump canceled the summit with Kim, scheduled for June 12 in Singapore, citing the “tremendous anger and open hostility” in a recent statement by North Korean diplomats.
