By mid-1995 the military situation became very tense again, and in August 1995 the BSA 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 BSA Command &amp; Control facilities and other targets. Also the BSA-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 BSA heavy weapons from the Sarajevo exclusion zone, effectively ending the Siege of Sarajevo.
