Soviet killer dolphins on the loose in the Black Sea

Using old Soviet Union techniques, Ukrainian scientists trained dolphins to attack and kill swimmers using knives and guns strapped to the heads of said dolphins. Like you do. Today, the dolphins escaped. No word on whether they are armed. (Is it just me, or does this sound like the set-up to a cheapo Eastern European "B" horror movie? I'm imagining screaming spring breakers fleeing evil cetaceans. Day of the Dolphin?) Maggie
