Huge crowds surged into the streets of Georgia's capital to demonstrate against Russia on Monday. It appears that up to 100,000 protesters jammed Tbilisi's main avenue, though no official turnout figures were immediately available. They shouted the country's name in Georgian: Sa-kart-ve-lo. Meanwhile others were protesting at a Russian checkpoint where soldiers are guarding the "security zone" Moscow claimed for itself after last month's war. The Tbilisi demonstration started Monday with people holding hands to form "human chains" in an echo of the so-called Baltic Chain of 1989 in which residents of then-Soviet Lithuania, Latvia and Estonia stretched the length of their homelands to protest Soviet occupation.
