U.S.-backed Prime Minister Ayad Allawi was trailing a Shiite ticket with ties to Iran in Iraq's historic election, according to partial returns released Friday. Three U.S. soldiers were killed and 12 wounded in the north, and gunmen seized an Italian journalist in Baghdad. The United Iraqi Alliance, endorsed by Iraq's top Shiite clerics, captured more than two-thirds of the 3.3 million votes counted so far, the election commission said. The ticket headed by Allawi, a secular Shiite, had about 18 percent - or more than 579,700 votes. Those latest partial figures from Sunday's contest for 275 National Assembly seats came from 10 of Iraq's 18 provinces, said Hamdiyah al-Husseini, an election commission official. All 10 provinces have heavy Shiite populations, and the Alliance had been expected to do well there. So far, 45 percent of the vote has been counted in Baghdad, with varying percentages tallied in the other nine provinces. Nevertheless, the huge lead that the Shiites were rolling up among their core constituency in the Shiite heartland of southern Iraq pointed to the likelihood of a tremendous victory, according to a report of the Associated Press.
