Georgian troops have pulled out of the capital of the breakaway province of South Ossetia under massive Russian shelling, a Georgian minister said Sunday morning. Georgia's Reintegration Minister Temur Yakobashvili said the Georgian troops left Tskhinvali on Sunday to change their location. Yakobashvili said Georgian troops remained in South Ossetia. He said the pullout would help provide a humanitarian corridor to evacuate those wounded from Tskhinvali. The city has been ravaged by fierce battles since Friday when Georgian troops launched an offensive to regain control over South Ossetia.
