Private homes and tea-houses were ablaze in a densely populated ethnic Uzbek neighbourhood in southern Kyrgyzstan's city of Osh on Friday, and frequent gunfire was heard, a Reuters eyewitness said. "The Uzbek-populated neighbourhood, Cheryomushki, is on fire," she said by telephone from the Central Asian state's second-largest city, according to Reuters. "Clashes are flaring up between ethnic Kyrgyz and Uzbeks. Many people are building barricades."
