Rival Koreas Scramble Warplanes In Extension Of Tensions

South Korea scrambled about 80 military aircraft, including advanced F-35 fighter jets, on Friday after tracking about 180 flights by North Korean warplanes inside North Korean territory in what appeared to be a defiant show of strength.

North Korea’s mobilization of warplanes came after it test-fired around 30 ballistic missiles over the previous two days, including an intercontinental ballistic missile on Thursday that triggered evacuation warnings in Japan, in an angry response to ongoing joint exercises by hundreds of U.S. and South Korea military planes.

Later Friday, North Korea’s Foreign Ministry called its military actions this week an appropriate response to the joint exercises, which it described as a display of U.S. “military confrontation hysteria.” It said North Korea will respond with the “toughest counteraction” to any attempts by “hostile forces” to infringe on its sovereignty or security interests.

South Korea’s Joint Chiefs of Staff said the North Korean warplanes were detected in various areas inland and along the country’s eastern and western coasts, but did not come particularly close to the Koreas’ border. The South Korean military spotted about 180 flight trails from 1 to 5 p.m., but it wasn’t immediately clear how many North Korean planes were involved and whether some may have flown more than once.

None of the planes breached the South Korean military’s virtual “tactical action” line, which is 20 to 50 kilometers (12 to 30 miles) north of the Koreas’ land and sea boundaries and is used for monitoring purposes to give the South enough time to respond to provocations or attacks.

South Korea still scrambled about 80 of its own warplanes, including an unspecified number of F-35 fighters. There weren’t any immediate reports of clashes.
