U.S. President Donald Trump on Thursday called off his planned June 12 summit meeting with North Korean leader Kim Jong Un in a letter released by the White House.
"I was very much looking forward to being there with you," Trump said in the letter. "Sadly, based on the tremendous anger and open hostility displayed in your most recent statement, I feel it is inappropriate, at this time, to have this long-planned meeting."
Trump called it "a missed opportunity" and said someday he still hoped to meet Kim.
Earlier Thursday, North Korea repeated a threat to pull out of the unprecedented summit with Trump next month and warned it was prepared for a nuclear showdown with Washington if necessary.
In a statement released by North Korean media, Vice Foreign Minister Choe Son Hui had called U.S. Vice President Mike Pence a "political dummy" for comparing North Korea - a "nuclear weapons state" - to Libya, where Muammar Gaddafi gave up his unfinished nuclear development program, only to be later killed by NATO-backed fighters.
A small group of international media selected by North Korea witnessed the demolition of tunnels at the Punggye-ri site Thursday, which Pyongyang says is proof of its commitment to end nuclear testing.
The apparent destruction of what North Korea says is its only nuclear test site has been widely welcomed as a positive, if largely symbolic, step toward resolving tension over its weapons.
