Moscow: Russia will turn over to Poland copies of materials on the so-called Katyn case in which thousands of Polish nationals were executed in 1940 by the Soviet secret police NKVD -- People`s Commissariat for Internal Affairs.
"The copies of 20 volumes of the criminal case of the execution of Polish citizens in Katyn will be turned over to the Polish side at the Prosecutor-General`s Office on Thursday," a source in the Prosecutor-General`s Office said yesterday.
The materials are supplied to the Polish side at its request for legal aid.
In May 2010, the Prosecutor-General`s Office turned over to the Polish officials the first part of documents on the case.
The Polish side, specifically, received six boxes with volumes weighing 72 kilograms.
Moscow has earlier turned over archive documents to Warsaw, but this is the first time that materials of the Russian criminal investigation of the Katyn tragedy are referred to the Polish side this year.
The criminal proceedings were instituted in March 1990.
Russia`s Main Military Prosecutor`s Office conducted the investigation for 14 years and completed it in September 2004.
The materials of the case, specifically, contain information that the decision on executions was made in March 1940.
The executions were conducted from April to May 1940 and took place not only on the territory of Katyn but also near Kharkov, Kalinin (Tver), as well as in districts of western Ukraine and western Belarus.
The materials of the case contain over 16,700 pages.
The Polish side first made a request about the Katyn events back in 1943, and then in the late 1990s and early 2000s.
The remains of more than 4,400 executed interned Polish officers were buried in the Katyn forest 18 kilometres west of Smolensk in April-May 1940.
Everyone was identified.
Near the burials of Poles in the Memorial complex are the ashes of repressed Soviet citizens. According to historians, some 10,000 Soviet citizens are buried there.
