A watch tower stands in a museum commemorating victims of Soviet-era political repressions located in a former prison camp, some 110 kms (69 miles) northeast of the west Siberian city of Perm, Russia, Friday, March 6, 2015. Historians estimate that under Soviet dictator Josef Stalin, 700,000 people were executed during the peak of the purges in 1937-1938. Millions more died of harsh labor and cruel treatment in the giant Gulag prison camp system, mass starvation in Ukraine and southern Russia and deportations of ethnic minorities.
