North Korean leader Kim Jong Un said that were the South to violate less than a millimeter of his country's territory, it would be considered a provocation for war, state media said Tuesday.
North Korea said it successfully placed its first spy satellite in orbit on Tuesday and vowed to launch more in the near future, defying international condemnation from the United States and its allies.
North Korea's military said the launches were simulated strikes on South Korea and the United States, criticising their joint air exercises as an "dangerous, aggressive war drill."
