"It said shooting came from three ethnic Georgian villages, but Georgia blamed the separatists for provoking the clashes.
The commander of Georgia's peacekeeping force in the region, Mamuka Kurashvili, was quoted by Interfax news agency as saying South Ossetian peacekeepers shot at a Georgian village and suspected Russian peacekeepers of taking part.
Georgian peacekeepers and police officers returned fire and repelled the attack, he said.

"That scenario started unfolding in South Ossetia in late July. By August 6 and 7, heavily armed proxy troops opened fire on Georgian villages, while the secessionist authorities refused to talk with Tbilisi. The attacking forces began destroying the transmission antennae of Georgian mobile telephone systems. Arms and paramilitary groups poured in from Russia to South Ossetia through the Russian-controlled Roki tunnel. Russian officials in Georgia claimed that the attacking forces were out of Russias control. Officials in Moscow, meanwhile, justified the attacks directly and indirectly by accusing Georgia of aggression (Interfax, Itar-Tass, Russian Television, August 4-7)."
