The first legal action will be sent to the county court of Helsinki within a month, Klavdia Nyuppieva, chairperson of the Karelian Union of Former Prisoners of Nazism, told RIA Novosti.
If the action is not accepted, they will appeal to higher courts of Finland and the European Human Rights Court.
Former prisoners of Finnish concentration camps are going to demand compensations comparable in size to that paid by Germany to Russian citizens who suffered from German occupation.
Karelian war prisoners decided to demand compensations from Finland after they were refused at the Russian Fund for Mutual Understanding and Reconciliation, through which Germany pays compensations to Nazi victims.
The right to compensations belongs to only those kept in German concentration camps, in German-occupied territory or were deported to Germany, the Fund explained. Former prisoners of Finnish concentration camps are not ranked in this category.
According to the Karelian FSB, during the WWII there were 13 camps for civilians in Karelia, set up by the Finnish occupation authorities and called "resettlement camps".
In the official documents of the Karelian FSB, these camps are called "concentration camps" and ex-prisoners have the status of Nazi prisoners on a par with people kept in German concentration camps.
Today 5,500 people in Karelia have the status of former prisoners of Finnish concentration camps.
