Russian and Georgian forces have exchanged prisoners in a gesture of goodwill.
But Georgian officials complained the swop only went ahead because of Russian threats.
Georgian National Security Council Secretary, Kakha Lomaia said: “Last night they came up with an ultimatum. If the POWs are not exchanged, they will advance to Tbilisi. I mean, that was communicated to me verbally.”
But the commander of Russian forces in the region made no reference to any threat of an attack on the Georgian capital.
Russian Major-General, Vyacheslav Borisov said: “It was an exchange of POWs as both sides agreed. And it was in accordance with all international protocols.”
Fifteen Georgians, including two civilians, were handed over in return for five Russians soldiers.
Georgia said it believes Russia is still holding two of its soldiers captured during fighting for control of Tskhinvali.
