U.S. Navy and Air Force spy planes flew near North Korea several times in recent days, as Pyongyang condemned Washington's North Korea policy and the latest satellite imagery showed activity at Nampo shipyard.
Aircraft tracker RadarBox disclosed data of movements of the U.S. Air Force's Joint STARS E-8C aircraft and the U.S. Navy's EP-3E Aries. Both aircraft were deployed at the end of April, South Korean news service News 1 reported Tuesday.
The E-8C flew over the West Sea or Yellow Sea, between China and the Korean Peninsula on April 25, Wednesday and Thursday. The EP-3E flew over the Korean Peninsula on April 27. The timing of the flights coincided with last week's North Korea's Kimilsungist-Kimjongilist Youth League.
The tracker also showed both spy planes were deployed Sunday, when Pyongyang issued three separate statements critical of the United States and South Korea.
