Ukrainians are voting in a parliamentary election on Sunday, the BBC reports.
Polls opened at 08.00 (06.00 GMT) and pit a main opposition grouping against President Viktor Yanukovych's Party of Regions.
Polls will be open for 12 hours, and while some counts will come in very quickly, the final result is expected on Monday.
Half of the seats in the 450-member parliament will be filled by elected parties on a candidate list basis.
The other half will be filled by individual candidates voted in on a first-past-the-post system.
