Georgian officials said there were five explosions near the de-facto border between Georgia and its breakaway region of Abkhazia on Sunday, in the latest sign of growing tensions between Tbilisi and separatists.
A series of incidents in the past week, involving bombs, mortar shelling and shootouts have been matched by sharp condemnations from Moscow and Tbilisi, as both sides blame each other for thawing what had been frozen conflicts.
Georgia's rebel regions of Abkhazia and South Ossetia broke away from central rule during wars in the 1990s and are flashpoints for tensions with Russia, which provides financial support and has peacekeepers in both.
