WATCH: Footage of the destruction of tunnels at North Korea's only nuclear site
The destruction was undertaken in an attempt to reduce regional tensions.
At least three nuclear tunnels appear to have been destroyed at the Punggye-ri nuclear test site in North Korea on Thursday.
The information comes less than 24 hours after Donald Trump called off his summit with Kim Jong-un.
In a latter addressed to North Korea, Trump said: "You talk about your nuclear capabilities, but ours are so massive and powerful that I pray to God they will never have to be used."
Tom Cheshire of Sky News was at the scene in Pnggye-ri and has since posted videos of the destruction of the tunnels on Twitter.

Actually, though, a couple of buildings out of seven were left standing. Here’s the second attempt pic.twitter.com/ewJDhIS2S6

Final explosion: the third tunnel. Takes a fair chunk of hill with it. pic.twitter.com/tHXVboTnSR
