Crimean Bridge Blow - Video Analysis⚡️

▪️ A wave appears just before the camera cuts out for a moment, the truck is still intact

▪️ The explosion does not spread evenly away from the truck to all sides

▪️ There is an unevenly strong effect in the direction of the railway bridge

🔎 Based on the above circumstances, the truck is almost certainly not the cause of the explosion.
