The killing of an enemy admiral in a missile strike would be a coup for any military, but the celebration in Ukraine over the death of Russia¡¯s Black Sea fleet commander may turn out to be short-lived.

A day after announcing that the admiral was among 34 officers killed in a strike deep behind enemy lines, Ukrainian officials acknowledged Tuesday that there might be some uncertainty.

The Ukrainian military¡¯s statement that it was now ¡°clarifying¡± whether the admiral, Viktor Sokolov, had in fact been killed in an audacious strike last week in Russian-held Crimea came after Russia released a video Tuesday purporting to show the admiral attending a meeting earlier in the day.
