The siege of Sarajevo (Bosnian: Opsada Sarajeva) was a prolonged blockade of Sarajevo, the capital of Bosnia and Herzegovina, during the Bosnian War. After it was initially besieged by the forces of the Yugoslav People's Army, the city was then besieged by the Army of Republika Srpska. Lasting from 5 April 1992 to 29 February 1996 (1,425 days), it was three times longer than the Battle of Stalingrad, more than a year longer than the siege of Leningrad, and was the longest siege of a capital city in the history of modern warfare.When Bosnia and Herzegovina declared independence from Yugoslavia after the 1992 Bosnian independence referendum, the Bosnian Serbs—whose strategic goal was to create a new Bosnian Serb state of Republika Srpska (RS) that would include Bosniak-majority areas—encircled Sarajevo with a siege force of 13,000 stationed in the surrounding hills. From there they assaulted the city with artillery, tanks, and small arms. From 2 May 1992, the Serbs blockaded the city. The Bosnian government defence forces (ARBiH) inside the besieged city, approximately with 34,931 troops on average, without heavy weapons or armor, defended much of the urban area of the city throughout the war but were unable to break the siege. The siege was lifted following the signing of the Dayton Agreement on December 14th, 1995. A total of 13,952 people were killed during the siege, including 5,434 civilians. The ARBiH sustained 3,587 fatalities, while Bosnian Serb military casualties numbered 2,241 killed soldiers. The 1991 census indicates that before the siege, the city and its surrounding areas had a total population of 525,980. According to some estimates, the total population of the city proper prior to the siege was 435,000. Estimates of the population of Sarajevo after the siege ranged from 300,000 to 380,000. Sarajevo's population endured up to six months without gas, electricity or water supply during certain stages of the siege.After the war, the International Criminal Tribunal for the former Yugoslavia (ICTY) convicted four Serb officials for numerous counts of crimes against humanity which they committed during the siege, including terrorism. Stanislav Galić and Dragomir Milošević were sentenced to life imprisonment and 29 years imprisonment respectively. Their superiors, Radovan Karadžić and Ratko Mladić, were also convicted and sentenced to life imprisonment. Source: Wikipedia (en)
