In the spring of 1989, Georgians took to the streets to demand independence from the Soviet Union. At the peak of the demonstrations, many thousands of people -- some of them on hunger strike -- gathered in central Tbilisi. On April 9, Soviet Interior Ministry troops moved in to crush the peaceful protests, killing at least 20 people and leaving hundreds injured or poisoned by gas. The crackdown became one of the turning points in the final years of the Soviet Union. (13 PHOTOS)
