View of the exhumed bodies of Polish officers murdered in the Katyn Forest Massacre by Soviet secret police (NKVD), Katyn Forest, Russia, 1943. In the background, bodies are autopsied. The massacre, which occurred in 1940, was discovered by German soldiers in 1943, and covered-up by Soviet forces shortly after--it was not acknowledged by the Russian government for nearly 50 years.
