– Chicago Tribune – An anti-submarine boat may have been the first casualty of the Russian incursion into Crimea, but it was hardly an act of violence, much less war: The Russian navy sank one of its own, junked vessels to create an obstacle, a Ukrainian official said Wednesday. Ukraine Defense Ministry spokesman Lt. Col. Alexei Mazepa said Russian sailors pulled the anti-submarine vessel Ochakov out of a naval junkyard and sank it in the straits that connect the Black Sea with a body of water known as Donuzlav Lake. He said the act was intended to prevent Ukrainian navy ships from leaving a nearby base and going to sea.
