Still relatively earlier, so take these as preliminary (coming from admin source):

14.27 million registered voters in and outside Iraq.; 5,159 polling centers; 184,000 local officials working at the 5,159 centers; Approximately 45,000 local Iraqi monitors and 199 international monitors. Total of 53,000 – 55,000 monitors; in 14 countries nearly 187,000 Iraqis voted in the first two of three days of voting for Iraqis abroad. This is 65.86% of all Iraqis who registered to vote abroad. Roughly two-thirds of Iraqis in the US who registered voted in the first two days of OCV voting.
