Russia deploys S‑300 defense system near Estonian border after mysterious fire

The recording, posted on the X platform, reveals the transfer of the S-300 anti-aircraft system to Petersburg, a city lying approximately 93 miles from the Estonian border.

This equipment was transported following a fire in the Baltic port of Ust-Luga, roughly 62 miles from Petersburg. Regional residents reported hearing explosions prior to the fire; the Kremlin has accused Ukraine of causing the incident.

Originating from Soviet times, the S-300 system was primarily used as an air defense system. However, it's now also being used in strikes on Ukrainian cities.
