Russian aircraft became more active shortly after that, and a wave of air raid alerts ran across Ukraine’s territory.

The South Operational Command urged civilians to follow the alert messages and react promptly and accordingly.

“The missile threat is obviously increasing,” the South Operational Command warned.
