Japan and South Korea put fighter jets in the air on Wednesday, November 30, because of overflights over the Sea of Japan by Chinese bombers and Russian warplanes, Interfax-AVN reported, citing statements by Japan's Joint Chiefs of Staff and South Korea's Joint Chiefs of Staff.

According to the agency, Japanese Air Defense Forces noticed two Chinese H-6 bombers moving through the Tsushima Strait from the East China Sea over the Sea of Japan toward the mainland. At the same time, two Russian warplanes were approaching them and then turned around and flew north.

The South Korean command took F-15K fighters into the air, believing that they had entered South Korea's air defense zone, which extends beyond the country's airspace.
