Polls in Iraq will be closing in 5 minutes at 6pm local time.
There have been conflicting reports as to voter turn-out so far, with some predicting a total of around 36 percent.
With the last citizens still registering their votes, an Iraqi election monitoring organisation has spoken of "violations" during the ballot.
"Observers from our organization have registered a number of election violations," Ali al-Dejili, head ofIraqi election monitoring NGO Tammuz, told Anadolu Agency.
He said violations had included campaigning by candidates outside polling stations and encouraging voters to select specific lists outside polling stations.
Al-Dejili said the irregularities had been registered in a number of provinces, including the western Anbar province, the northern Nineveh province and some southern provinces.
He also said that voter turnout has risen throughout the day, after being recorded at around 20 percent at midday.
