South Korea scrambles jets after Russian military planes enter air defence zone

South Korea said on Wednesday it had scrambled fighter jets in response to Russian military aircraft entering its air defence zone, the second such incursion in weeks. The relationship between the countries has worsened since South Korea joined Western sanctions following Russia’s invasion of Ukraine, and since Moscow built stronger ties with North Korea. Seoul’s defence ministry said multiple Russian aircraft had entered and then left its air defence identification zone over the East Sea, also.
