Part of voters is not included in voter lists in Kyrgyzstan, CIS Observation Mission Headquarters Deputy Chief Oleg Kuleba said on Sunday.
"According to the CIS observers' data available every two hours, the main problem of voters is that citizens can not find their data on voter lists," Kuleba said.
He said "such violations are prevailing in Bishkek, Chui and Issyk-Kul regions," KyrTAG reported.
"These citizens can not exercise their constitutional right as a result of imperfection of the current electoral law, which eliminates additional lists, as well as the lack of other forms in order to prevent similar incidents," he said.
"Our observers did not confirm the report that poor marking is used in some polling stations. In general, the situation is stable in the republic, violation of the electoral process is not observed", Kuleba said.
Some 177 short-term CIS observers have been accredited to Kyrgyzstan for presidential elections, 60 of which are working in Bishkek, while the rest of the observers are patrolling the territorial polling stations.
Presidential elections started in Kyrgyzstan at 8:00 local time on Sunday.
Under the new Constitution, the President of Kyrgyzstan is elected for six years and only one term.
Some 2,289 polling stations, as well as 29 polling stations in 23 countries will operate to hold the presidential elections in Kyrgyzstan.
To date, the country registered a little over 3 million voters.
The elections are being observed by 792 international observers from 56 countries.
