The strike was inflicted, presumably, on an oil refinery.
"Today, enemy UAVs attacked an industrial enterprise in Syzran. In the city, the public was alerted to the threat of an attack using sirens and voice announcements through loudspeakers. According to preliminary data, there are no dead or injured as a result of the attack," the governor said.
The "Carpet" mode operates on the territory of the Samara region. The airspace is temporarily closed.
