Osmanagićeve tunele -- od kojih je jedan otkriven u blizini jedne stare fabrike -- iskopali su rudari tokom srednjeg vijeka, kažu skeptici, dodajući da je i bivša Jugoslavenska armija bila dobro upozanata s njihovim postojanjem.
Osmanagic's tunnels -- one of which was discovered next to an old factory -- were dug by miners during the medieval era, skeptics say, adding that the former Yugoslav Army was well aware of their existence.
