Troops cordon off the parliament building in Tbilisi, Georgia, on Thursday Nov. 8, 2007, with Georgian flag flying at right, and European flag left. Troops flooded the center of the Georgian capital on Thursday to enforce a state of emergency imposed after a violent crackdown on anti-government protesters. President Mikhail Saakashvili announced a 15-day nationwide state of emergency late Wednesday after riot police used tear gas, rubber bullets and water cannons against thousands of demonstrators calling for Saakashvili to resign.
