Kyrgyz Army volunteers are alert in the back of a truck patrolling the outskirts of the southern Kyrgyz city of Osh in Kyrgyzstan, Wednesday, June 16, 2010. Heavy arms fire rang out over the Kyrgyz city of Osh before dawn Wednesday as authorities struggled to bring order to the country's south, which has been thrust into chaos by days of deadly ethnic riots. The violence has prompted more than 100,000 Uzbeks to flee for their lives to Uzbekistan, with tens of thousands more camped on the Kyrgyz side or stranded in a no man's land.
