International observers have backed Kyrgyzstan's referendum on a new constitution, describing it as largely transparent and peaceful. With nearly all ballots counted, the electoral commission said voters had overwhelmingly approved the changes, which will give parliament more power. The interim government called the vote after President Kurmanbek Bakiyev was overthrown in April. The referendum took place about two weeks after a wave of fighting between ethnic Kyrgyz and Uzbeks in the south, in which officials fear up to 2,000 people may have been killed.<br/>
