Interim leader Rosa Otunbayeva has been sworn in as president of the Central Asian republic of Kyrgyzstan.
Mrs Otunbayeva took power after street riots in April which ousted President Kurmanbek Bakiyev. She took the oath of office in a concert hall in the capital Bishkek.
A referendum was held last Sunday on a new constitution which will create the region's first parliamentary democracy.
The Central Election Commission said that more than 90% of ballots cast in Sunday's referendum were in favour of the constitution.
Meanwhile, the BBC reports ethnic violence in the south of the country has abated, but the Uzbek and Kyrgyz populations remain deeply divided.
Mrs Otunbayeva has said as many as 2000 people died in rioting in and around the city of Osh last month. An estimated 400,000 people were displaced.
