Falling debris from destroyed Ukrainian drones disrupted railway power supply in part of the Volgograd region, the administration of the region in Russia's south said on Sunday.
There were no injuries as a result of the Ukrainian attack, the administration said on the Telegram messaging app, citing Governor Andrei Bocharov.
Russia's civil aviation authority Rosaviatsia said on Telegram that it had suspended flights soon after midnight on Sunday at the airport in the city of Volgograd, which is the administrative centre of the broader Volgograd region.
The extent of the damage and the scale of the attack were not immediately clear. Air raid alerts were introduced also in several other regions in Russia's west and south, warning of a Ukrainian drone attack, according to Telegram posts by regional officials.
