Quote: “I am grateful to our defenders of the sky – just today a Russian aircraft was shot down in the area of Zmiinyi Island in the Black Sea. The aircraft was attempting to strike Odesa Oblast. Another minus one for the terrorists. And we will continue to ‘subtract’ the terrorists. We are strengthening our air defense, particularly in Odesa Oblast. Gradually. Yet tangibly. I thank every country that helps.”
