Mount Igman became in the course of the 1991-95 conflict suddenly an area of major strategic importance as part of the 1992-1995 Siege of Sarajevo . The predominantly Bosniak villages of Hrasnica and Butmir held out as an ARBiH stronghold between the BSA-held villages of Ilidža and Vojkovići , forming a corridor connecting the slopes of Mt Igman with the UN-controlled airport of Sarajevo . After the completion of the Sarajevo Tunnel under the airport in July 1993 , the small unpaved forest road passing over Mt Igman became the sole important supply road into the besieged city . The ARBiH-controlled 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 . A major BSA offensive started July 1993 and on August 4 , 1993 Serb forces captured part of the Igman supply road . The BSA advance was stopped under threat of NATO airstrikes . The area was declared a Demilitarized Zone ( DMZ ) by the UN after the BSA retreated and UNPROFOR units were stationed on Igman and nearby Bjelašnica . The supply road into Sarajevo was agreed to be used for humanitarian goods only , but ARBiH logistical activity on the road and through the tunnel continued nevertheless . Discussion about real or alleged reluctance to withdraw ARBiH forces from the DMZ was a growing issue between UNPROFOR Commander General Rose and ARBiH Commander General Delić , with BSA Commander Mladić waiting for an opportunity to close the gap . Trucks on the Igman supply road 's narrow last stretch descending the steep north-eastern slope became fully exposed to fire from BSA artillery positions in Ilidža and Vojkovici . Meanwhile , the ARBiH units remaining on the plateau were formally restricted to R&R activities , notably resulting in the building of the Igman Dzamija , a wooden mosque in the forest , still much frequented today . The Igman supply road remained the almost exclusive supply route into Sarajevo until the end of the war . It was also the only entry and exit road for the Bosnian political leadership . Bosnian president Alija Izetbegović and foreign secretary Muhamed Sacirbey traveled this road . Foreign negotiators tended to avoid the road as it was " often described as the most dangerous road in Europe " . Forced by a Serb blockade of the Sarajevo Airport , on August 19 , 1995 , a US Peace Mission headed by Richard Holbrooke took this road in order to reach Sarajevo for a meeting with the Bosnian presidency . Holbrooke decided to sit with General Wesley Clark in a Humvee , while the other members of the delegation travelled in a French UNPROFOR Renault VAB Armored Personnel Carrier . At a particular exposed and narrow point - now marked by a French memorial plaque - the French APC went over the edge and rolled and tumbled down some 400 metres . US Diplomats Robert Frasure , Nelson Drew and Joe Kruzel as well as the French Corporal-driver perished in the incident . The battered APC is still to be seen where it ultimately came to a halt - next to a memorial site for the victims . By mid-1995 the military situation became very tense again , and in August 1995 the BSA launched another offensive forcing UNPROFOR from the Bjelašnica ridge and advancing again towards Veliko Polje . After the second Markale shelling , on August , 30 NATO started Operation Deliberate Force , in which NATO aircraft engaged BSA Command & Control facilities and other targets . In conjunction with these attacks a Rapid Reaction Force consisting of units of the British 19th Reg . Royal Artillery , the French 2nd Legion Etranger d'Infanterie and the Dutch 1e Mortiercompagnie of the NL Marine Corps , was deployed on Igman with ( RNLA ) search radars and heavy artillery , engaging any actively firing BSA artillery installation around Sarajevo until 14 September 1995 , when the NATO air strikes were suspended to allow the implementation of the withdrawal of BSA heavy weapons from the Sarajevo exclusion zone , effectively ending the Siege of Sarajevo . A number of memorials and war cemetery sites is found throughout the Igman plateau
