It is premature to say voters in Kyrgyzstan approved the new constitution, the head of the country's Central Election Committee told journalists on Sunday, RIA Novosti.
"It is as yet too early to say that the constitution has been adopted, and no one has any data on which to base such a claim," Akylbek Sariev said.
The head of the interim government, Roza Otunbayeva, declared that the new constitution had been adopted as the first preliminary results were reported.
With 32 percent of precincts returning, the CEC said on its website that 89.35 percent of voters had approved the new constitution and just 9.28 percent opposed it.
Sariev said turnout was 69.15 percent and reported that one polling station in Bishkek had run out of ballots.
"There was a case of a lack of ballots of about 100 papers, as in this section a lot of people wanted to vote on additional lists," he said.
He added that additional ballots were brought from a neighboring precinct.
The referendum was held against a background of recent ethnic unrest in the south of the country but authorities said it passed off with no major problems.
