The zones are near the border with separatist South Ossetia, the disputed province at the heart of the conflict that has ruined Georgia-Russia ties and caused the biggest crisis in Moscow's relations with the West since the 1991 Soviet collapse.
Fighting broke out Aug. 7 after Georgian forces launched a barrage on the South Ossetian capital of Tskhinvali, hoping to retake control of the province. Russian forces poured in, pushed the Georgians out in a matter of days and then drove deep into Georgia proper.
The United States has sent substantial aid to Georgia in the wake of the war, using naval ships and military aircraft. Russian officials raised speculation that the military involvement could indicate the United States was seeking to restore Georgia's armed forces, which had received massive military aid from Washington in recent years.
