Nothing new, except for this tidbit:
North Korea threatened on Tuesday to abandon the 1953 armistice that ended the Korean War
...
North Korea "will be left with no option but to take a decisive step to abandon its commitment to implement the Armistice Agreement ... and free itself from the binding force of all its provisions," said the official.
The 1950-53 Korean War ended with the armistice, not a peace treaty, leaving the countries technically in a state of war. A North Korean withdrawal from the armistice would greatly increase tensions and uncertainty along the world's most heavily armed border.
