 According to University of Amsterdam professor 'C.Wiebes', the Hellenic National Intelligence Service (EYP) systematically sabotaged NATO operations in Bosnia in the mid-1990s, in an attempt to aid Bosnian Serb nationalists.In his report for the Dutch government, entitled "Intelligence en de oorlog in Bosnie 1992-1995", Wiebes claims that EYP leaked classified NATO military plans (to which, as an allied intelligence service, it had access) to the Serb Bosnian leadership, and often to General Ratko Mladić himself, during the summer of 1995.
