Destruction of Jews by militants of the Organization of Ukrainian Nationalists and the Front of Lithuanian Activists in the summer of 1941; punitive operations of the Nazis and their accomplices in the occupied territory of the Soviet Union; repressive campaigns of the NKVD in the Baltic states. These and other pages of the tragic history of the "elimination of the hostile element" are described in the book of the director of the Historical Memory Foundation Alexander Dyukov.
