A US guided-missile submarine arrived in South Korea on Tuesday and envoys from the US, Japan and South Korea met in Tokyo, as North Korea prepared to mark the anniversary of the founding of its military.
Although a major event around the anniversary was viewed as possible, the morning came and went without any nuclear tests or ballistic missile launches. All that was publicly scheduled for the day were gatherings for mass dancing, a common celebration on major North Korean holidays.
"The situation prevailing on the Korean peninsula is so tense that a nuclear war may break out due to the frantic war drills of the US imperialists and their vassal forces for aggression,'' he told the gathering.
North Korean leader Kim Jong Un did not attend. It was not known how he was marking Tuesday's anniversary.
North Korea often marks significant dates by displaying its military capability and has conducted five nuclear tests. Pyongyang launched a missile one day after the 105th birthday of late founder Kim Il Sung on April 15.
Such a move could test the developing North Korea policies of President Donald Trump, who has reportedly settled on a strategy that emphasizes increased pressure on North Korea with the help of China, the North's only major ally, instead of military options or trying to overthrow North Korea's government.
