Insurgents attacked Shi'ite Muslims in and around Baghdad on Friday, killing at least 31 people and wounding dozens more in five separate attacks. In two of the attacks, suicide bombers approached worshippers leaving Friday prayers at two mosques and detonated explosives. In another attack, a mortar shell landed on a cafe near a mosque in a Shi'ite neighborhood. A fourth blast occurred at an Iraqi police and National Guard checkpoint. And the latest bombing came outside a Shi'ite mosque south of the capital (in Iskandariya). The attacks come during the holiest period in the Shi'ite calendar, known as Ashura, and one day after certified election results solidified Shi'ite dominance in the new National Assembly. In other violence, the U.S. military says one soldier was killed and two wounded in a roadside blast today near Baghdad.
