Four suicide bombers blew themselves up Saturday, killing at least five people, in the latest wave of violence to mar the most important holiday in the Muslim calendar. The attacks came one day after insurgents killed 36 people. Saturday's bombings, during the religious festival of Ashoura, came despite stepped-up security around the country. Authorities had hoped to prevent a repeat of last year's attacks during Ashoura in which insurgents killed at least 181 people in twin blasts in Karbala and Baghdad.
