South Korea Scrambles Jets as Russian Military Planes Enter Air Defense Zone

South Korea's military scrambled fighter jets on Wednesday in response to Russian military aircraft entering its air defense identification zone (ADIZ) over the East Sea, also known as the Sea of Japan. This incident marks the second such incursion in recent weeks, further straining relations between Seoul and Moscow.

The South Korean defense ministry stated that multiple Russian aircraft entered and subsequently exited the ADIZ. "South Korea's military detected the Russian aircraft before they entered the zone and deployed Air Force fighter jets to prepare for any contingency," the ministry said, emphasizing that the aircraft did not violate South Korean airspace. An ADIZ is a buffer zone where foreign aircraft are expected to identify themselves for security, though there is no legal obligation to notify authorities before entry.

This latest event occurs against a backdrop of deteriorating relations between South Korea and Russia. Ties have soured since Seoul joined Western sanctions against Russia following its invasion of Ukraine. Concurrently, Moscow has strengthened its ties with North Korea, a development that has heightened regional security concerns.

In late June, a similar incident involved more than 10 Chinese and Russian military aircraft entering South Korea's ADIZ. At the time, Beijing and Moscow described the flights as a "strategic air patrol" part of normal military cooperation, not directed against third countries. However, Seoul lodged protests with both Beijing and Moscow, demanding measures to prevent future occurrences.
