The interim leader of Kyrgyzstan, Roza Otunbayeva, has gone to the south of the country to try to ease tensions after last week's ethnic violence. A government spokesman said Ms Otunbayeva would meet local leaders and visit the injured. About 200 people were killed in the clashes between Uzbek and Kyrgyz groups and hundreds of thousands fled their homes, some going into neighbouring Uzbekistan. The top American official for Central Asia, Robert Blake, has arrived in the Uzbek border town of Andijan to visit refugee camps.
