Was that the dam the ukranians used to cut off the water supply to Crimea (one of the key acts that provoked the war in the first place)? Just wondering
No, it was the war criminal Vladimir Putin committing yet another crime against humanity and sensing the coming loss of the Crimea to a superior Ukranian army.
No, there were several dam incidents perpetrated by Ukraine to deny water to Crimea after the Crimean vote to join the Russian Federation.
The one you are most likely thinking of, was a smaller canal that was blocked by Ukraine Military and Engineers with a much smaller, new-construction dam.
Russian supported Crimean Troops eventually responded and opened the canal, while Putin began construction of the Crimean Bridge.
The dam in question is much larger, and controlled a very large reservoir that supplied many Ukraine farms, villages and towns, as well as safe river traffic by controlling a proper water level.
The Ukraine Military conducted explosive projectile tests against the dam to determine if they could damage the Independent Oblasts without damaging Ukrainian farm production and water supply.
They determined that they could not, and discontinued the test shelling.
Until now.
