result of the construction of the Sarajevo tunnel. A major VRS offensive started on July 1993 that led to the fall of Trnovo, and on 4 August 1993, Serb forces captured the Bjelašnica summit and part of the Igman supply road. The VRS advance was stopped under threat of NATO airstrikes. After tense negotiations the VRS retreated from the Bjelašnica summit, but not without blowing up the communications tower first. French United Nations Protection Force (UNPROFOR) units were stationed on Bjelašnica, and the Igman area was declared a Demilitarized Zone (DMZ) by the UN. The situation around the frontlines in nearby Treskavica and around Babin Dol, remained explosive with violent exchanges of hostilities between VRS and ARBiH units. The villages on the southern slopes of Bjelašnica, like Umoljani and Lukavac were not in the frontline, but sustained heavy damage from shelling. Discussion about real or alleged use by ARBiH forces of the Igman DMZ was an issue of constant contention, between UNPROFOR Commander General Michael Rose, ARBiH General Rasim Delić, and VRS Commander Ratko Mladić. By mid-1995, the military situation became very tense again, and in August 1995 the VRS launched another offensive, forcing UNPROFOR from the Bjelasnica ridge and advancing through Babin Dol towards Veliko Polje. However, after the second Markale shelling, on August, 30, NATO started Operation Deliberate Force, in which NATO aircraft engaged VRS Command & Control facilities and other targets. Also the VRS-held radar station on Vlahinja ridge was completely destroyed during these air strikes that lasted until 14 September 1995, when the air strikes were suspended to allow the implementation of the withdrawal of VRS heavy weapons from the Sarajevo exclusion zone, effectively ending the Siege of Sarajevo. Mine risks Extensive de-mining activities have taken place around recreational areas and especially around the existing ski runs, which can be considered safe by all means. The largest part of the Bjelašnica range remained largely spared from warfare and the mine risk is therefore minimal within the area west of the Bjelašnica summit and east of the Hranisava mountain. Gallery Bjelašnica Olympic Mountain Ski Centre The Bjelašnica Olympic Mountain Ski Centre and its facilities are all located on the eastern slope of Bjelašnica main summit. There are 6 lifts, with one modern three-seat carrier lift departing from Babin Dol, three anchor lifts and two remaining single saucer lifts. Next to the original 3100 meter Olympic Downhill run
