The poll's complicated ballot - some 6,200 candidates competed for 325 parliamentary seats - means the count could take a long time.

Election officials earlier said initial results were to be released by Tuesday evening, after about 30 percent of the ballots had been tallied. They later backed off from that announcement.

The commission's Qassim Al-Aboudi said instead that “ballots were still being processed” and that partial results would be released Wednesday evening.

Iraqis defied insurgent attacks that killed 36 people to cast ballots Sunday.
