North Korean leader Kim Jong Un made good on his promise to demolish his country's nuclear test site, which was formally closed in a series of huge explosions Thursday as a small group of foreign journalists watched.
The explosions at the test site deep in the mountains of the North's sparsely populated northeast were supposed to build confidence ahead of a planned summit next month between Kim and President Donald Trump. But Trump canceled the meeting on Thursday, citing "tremendous anger and open hostility" in a North Korean statement released earlier in the day.
