Iraqi police say a car bomb has exploded in a Shi'ite village north of Baghdad, killing at least 25 people. Officials say the blast hit the small town of Howaider, near Baquba, around sundown on Saturday as families gathered at the mosque for evening prayers before breaking their Ramadan fast. Hospital officials say 40 people were wounded, some of them seriously. Elsewhere, a roadside bomb killed two Iraqi policemen near Kirkuk, and the U.S. military reported the deaths of three more American soldiers. The violence erupted as campaigning began for December's parliamentary elections, which will elect a new 275-member assembly to a four-year term. Election commission officials say more than 200 coalitions and candidate lists representing Iraq's many religious and ethnic groups registered by Friday's deadline to contest parliament's 275 seats.
