Amidst rising ethnic tensions, war broke out when Georgian forces entered the capital of South Ossetia, Tskhinvali. Military conflict began in January 1991, and urban warfare in Tskhinvali lasted until June 1992. More than 2,000 people are believed to have been killed in the war. The separatists were helped by former Soviet military units, who by now had come under Russian command. Approximately 100,000 Ossetians fled Georgia proper and South Ossetia, while 23,000 Georgians left South Ossetia. A ceasefire agreement (the Sochi Agreement) was reached on 24 June 1992. While it ended the war, it did not deal with the status of South Ossetia. A Joint Control Commission for Georgian–Ossetian Conflict Resolution and peacekeeping force, composed of Russian, Georgian and Ossetian troops, was set up. The Ossetian "de facto" government controlled the region independently from Tbilisi. The JPKF's activities were mainly concentrated in the Conflict Zone, which included an area within a 15-km radius from Tskhinvali.
