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.
