"Russian and Syrian military personnel restored the destroyed al-Jarrah airfield," the ministry said on the Telegram messaging app.
"The joint basing of aviation of the Russian Aerospace Forces and the Syrian Air Force at the al-Jarrah airfield makes it possible to cover the state border."
The small base east of Aleppo was recaptured from Islamic State fighters in 2017.
Russia has been a dominant military force in Syria since launching air strikes and ground operations there in 2015. It further asserted its presence after the United States pulled out its forces in 2019.
