7. Tbilisi, Georgia
Located on the Black Sea north of Russia, Georgia has long been plagued by crime and violent protests, such as a car bomb attack on the Israeli Embassy in February. Civil unrest peaked during the economic crisis in the 1990s and lasted until the Rose Revolution of 2003. Last week saw the worst upsurge on violence on the Russian-Georgian border since 2008, following a clash between between Georgian security forces and a bandof North Caucasian fighters that killed 12.
