S.Korea scrambles jets after Chinese, Russian warplanes enter air defense zone
South Korea's military said it scrambled fighter jets after at least four Chinese and four Russian warplanes entered its air defence zone on Tuesday.
The Russian and Chinese aircraft entered and left the Korea Air Defence Identification Zone (Korea ADIZ) in the Sea of Japan, known in Korea as the East Sea, several times through the day, according to South Korea's Joint Chiefs of Staff (JCS).
The aircraft, which included fighter jets and bombers from each side, did not violate South Korea's airspace, the JCS added.
The South Korean military deployed air force fighters to "implement tactical measures" to brace for a potential contingency.
