A Russian tourist who gave away the military position of Vladimir Putin's forces as he posed for a holiday snap in speedos has been "thanked" by the Ukrainian defence ministry.
The middle-aged man was standing in front of an S-400 air defence system and waving for the camera near the coastal city of Yevpatoria, in western Crimea.
Since the photo was posted, the Ukrainian defence ministry poked fun at the man in speedos and said "keep up the good work", for showing them where the Russian military units were.
