The meeting was held amid a prolonged deadlock in negotiations with the United States over the North’s nuclear program.

Defense Secretary Jim Mattis addressed the peace talks Friday at the Pentagon.

North Korea said U.S. pressure had nothing to do with its peace overtures to the U.S. and South Korea.

It is unclear whether U.S. aircraft carriers and nuclear submarines would participate as they have in previous war games.

The U.N. Command said in a statement it was investigating if there was a violation of an armistice that ended the Korean War.

The exchange of gunfire comes after Kim Jong Un had made his first public appearance in nearly three weeks.

As the absolute leader of a country with a nuclear weapons program, Kim's health is matter of intense interest.

Questions about the North’s political future are likely to grow if he fails to attend upcoming public events.
