Airport closed in Volgograd, Russia; drone hits industrial facility in Rostov region

On the morning of 21 November, the Russian Civil Aviation Agency temporarily closed Volgograd airport.
This was reported by Censor.NET with reference to Russian media.
The Rosaviatsiya statement, quoted by Russian agencies, said that this was done "to ensure flight safety". Usually, Rosaviatsiya closes airports in case of a threat of Ukrainian drones striking targets in the nearest area.
There have been no reports of drones flying overhead or being shot at by air defence systems. Rosaviatsiya later resumed the airport's operation.
In the Rostov region, a Ukrainian drone hit an industrial facility, said the region's governor, Yuri Slyusar.
It is noted that a fire broke out at an industrial facility in the Konstantinovsky district as a result of a Ukrainian drone crash. The governor claims that the fire was quickly extinguished.
Prior to that, Slyusar wrote on his Telegram channel that at night, one Ukrainian drone was shot down over the Myasnikovsky district of Rostov region.
