Dramatic footage has emerged of North Korea reportedly destroying its nuclear test site - just as Donald Trump scrapped a highly anticipated summit with Kim Jong Un.
The clips shows a huge blast in the countryside, leaving behind piles of rubble and a large dust cloud while invited western journalists looked on.
Sky News, the only British broadcaster invited, said it had witnessed what North Korea claims to be the destruction of its nuclear test tunnels at Punggye-ri.
Sky's Tom Cheshire said: "We hiked up into the mountains and watched the demolition about 500 metres away.
"There was a huge explosion, you could feel it.
"Dust came at you, the heat came at you. It was extremely loud."
