The incident reportedly began when a Russian military truck ran into the car of a Georgian resident in the conflict zone. No one was injured, but the car was damaged.
Fistfights broke out when Georgian police tried to take the truck to a police station in the town of Gori. One report says shots were fired into the air to stop the clashes.
South Ossetia proclaimed its independence in the early 1990s, triggering an armed conflict with Georgia. The cease-fire agreement that followed is being monitored by peacekeepers from Russia, Georgia, South Ossetia, and North Ossetia.
