The 18 September 2007 issue featured a sheet devoted to the Polish film '' Katyń '' , directed by Andrzej Wajda , about the 1940 Katyn massacre . A short comment by Alexander Sabov was published , claiming that the widely accepted version of Soviet responsibility is based on a single dubious copy of a document , therefore evidence for it is not reliable . Subov 's comment immediately provoked media frenzy in Poland , and on the following day the issue of the Polish newspaper '' Gazeta Wyborcza '' published relevant documents signed by Lavrenty Beria authorizing the massacre
