Following the entry of seven Russian and two Chinese military aircraft into its air defense zone on Tuesday, South Korea reportedly launched fighter fighters. According to a statement from Seoul's Joint Chiefs of Staff, the Chinese and Russian planes entered the Korea Air Defence Identification Zone (KADIZ) at approximately 10 AM local time (0100 GMT).
They claimed that none of the aircraft had entered South Korean airspace.
"Fighter jets to take tactical measures in preparation for any contingencies" were sent in response, according to Seoul.
According to Yonhap, the military claimed that the aircraft entered and exited the area for an hour before departing.

The aircraft were detected prior to their entry into the air defense identification zone, which is a more expansive area outside of a nation's airspace where airplanes are monitored for security purposes.
Citing joint drills, China and Russia have routinely flown military aircraft into South Korea's air defense zone without warning since 2019.
When five Chinese and six Russian military aircraft passed through Seoul's air defense zone in November of last year, the city scrambled its jets.
Beijing and Moscow referred to the flights as "joint strategic air patrols" during similar instances that happened in June and December 2023 as well as in May and November 2022.
Since Moscow sent soldiers into Ukraine over four years ago, China and Russia have increased their military and defense cooperation.Additionally, both have historically supported North Korea, Seoul's fiercest adversary.
