"Alert air defense forces destroyed 12 enemy UAVs over the territory of the Ulyanovsk Region in the last two days. This is the first time our region has been subjected to an attack of such magnitude. We managed to avoid casualties and destruction thanks to the efforts of our military," the governor said.

The security measures implemented included the temporary shutdown of mobile internet, Russkikh noted. "Wired internet will continue to operate regardless of mobile internet shutdowns.
