The provincial capital of South Ossetia, Tskhinvali, lies in ruins as Russia sends hundreds of tanks into Georgia: Russian troops raid Georgian town; scores dead.

GORI, Georgia (AP) - Russia sent hundreds of tanks and troops into the separatist province of South Ossetia and bombed Georgian towns Saturday in a major escalation of the conflict that has left scores of civilians dead and wounded.

Georgia, a staunch U.S. ally, launched a major offensive Friday to retake control of breakaway South Ossetia. Russia, which has close ties to the province and posts peacekeepers there, responded by sending in armed convoys and military combat aircraft.

Russian Foreign Minister Sergey Lavrov told reporters in Moscow that some 1,500 people have been killed, with the death toll rising Saturday.
