On September 27 , 1993 the Abkhaz side violated the UN-mediated cease-fire agreement ( Georgian side had agreed to pull out all heavy artillery and tanks from Sukhumi in return for cease-fire ) by storming defenceless Sukhumi . The Confederates moved into Sukhumi and started to sweep through streets of the city . As the city was engulfed by heavy fighting , civilians took refuge in abandoned houses and apartment buildings . Some of the civilians of Georgian ethnicity were massacred after their discovery by the Confederates . By late afternoon the remainder of Georgian troops surrendered to the Abkhaz side . The majority of Georgian POWs were executed on the same day by Abkhaz formations and Confederates . Few civilians and military personnel managed to survive the massacre . The massacre continued for two weeks after the fall of Sukhumi ( See Ethnic cleansing of Georgians in Abkhazia )
