But Bjelašnica became in the course of the Bosnian War an area of major strategic importance as part of the 1992-1995 Siege of Sarajevo. The territory covered by the Bjelasnica range and the Igman plateau between Konjic and the United Nations-controlled Sarajevo Airport was from the outset of the conflict controlled by the ARBiH. By mid-1993, the central plateau of Igman came under increased Serb military pressure when the suspicion became stronger that the area had become a major logistical artery of the besieged city as a result of the construction of the Sarajevo tunnel.
