Quote: Georgian President Mikhail Saakasvili, who has called on reservists to sign up for duty, said "150 Russian tanks, armoured personnel carriers and other vehicles" had entered South Ossetia. "This is a clear intrusion on another country's territory. We have Russian tanks on our territory, jets on our territory in broad daylight," Reuters new agency quoted him as saying. "I must also tell you that Georgian forces have downed two Russian jet fighters over Georgia's territory." It appears to have happened under the cover of the Olympic Games opening ceremony.
