A warning sign is pictured behind a newly constructed fence along Georgia's de-facto border with its breakaway region of South Ossetia in the village of Dvani, about 120 km northwest of Tbilisi, October 4, 2013. The fence put up by Russian forces on the boundary between Georgia and South Ossetia has been a source of dispute between Russia and Georgia. The breakaway region recognized by Russia as independent had been the focus of a brief 2008 war between the two countries. REUTERS/David Mdzinarishvili (GEORGIA - Tags: POLITICS)
