Iraqis voted Monday in the first provincial council elections held in a decade, which were expected to strengthen the dominance of pro-Iranian Shiite Muslim groups.The vote comes at a time of widespread political apathy and disillusionment in the oil-rich country of 43 million that is still recovering from years of war and plagued by corruption.Polls closed as planned at 6:00 pm (1500 GMT), state media reported, with the election commission saying preliminary results were expected 24 hours later.
