North Korea will destroy its nuclear test site later this month, ahead of a summit with the United States, it said Saturday, pledging to blow up its tunnels in front of invited foreign media.
US President Donald Trump praised the North's decision to dismantle the Punggye-ri test site in a ceremony scheduled between May 23-25, the latest step in leader Kim Jong Un's charm offensive.
"Thank you, a very smart and gracious gesture!" Trump tweeted.
Dialogue brokered by Seoul has seen US-North Korea relations go from trading personal insults and threats of war last year to a summit between Kim and Trump due in Singapore on June 12.
