North Korea unleashed a series of massive explosions atin the northeast of the country, claiming . CBS News was the only US station network to witness.
At the entrance to Tunnel No. 2 of the Nuclear Test Site in North Korea, where they have conducted five of their six nuclear tests in recent years, they were seen to have explosives there. They plan to blow this up so they can not use it anymore.
With several big explosions North Korea showed a pretty big show. It claims it has now destroyed all test tunnels on its notorious Punggye-ri nuclear test site. There, since 2006, the regime has carried out all six nuclear explosions. Some external scientists say the site has been so badly damaged by previous tests that it was unusable. North Korea says that's not true.
It is said that Tunnel # 3 is relatively new and still usable, so it would be a real concession to equip it with explosives and blow it up.
So far, satellite photos are the only ones we've seen this top secret and heavily guarded site.
North Korea allowed us to run directly to the nuclear test tunnels and said there was no concern about radiation. They say they have never discovered here on the site. But the one thing they confiscated from our luggage was equipment to detect radiation.
The journey to the remote mountain slopes took nearly 15 hours, most of which were spent in this specially equipped North Korean train. In the dining car, the waiters wore white jackets and served a lavish 10-course meal. But in the sleeping quarters there were strict rules.
Government officials came by and said that a shadow had to be down all the time. Apparently they did not want us to look out the windows to see how people might live in North Korea.
They wanted us to see the explosions, but we can only confirm that they blew up the entrances to the tunnels. If the tunnels still exist within the mountain, this location may still be used for future nuclear testing.
