President Mikhail Saakashvili made the statement in a national security council meeting on Monday, about an hour after officials claimed Russian troops had captured Gori, about 60 miles west of the capital Tbilisi.
The news agency Interfax cited a Russian Defense Ministry official as denying the reports of the seizure.
But a top official at the Georgian embassy in Moscow, Givi Shugarov, said Russian troops appeared to be moving toward Tbilisi and he alleged Russia's goal was "complete liquidation" of the Georgian government.
