Baghdad, Feb 20, SPA -- Eight suicide bombers struck in quick succession Saturday in a wave of attacks that killed 55 people. Ninety-one people have been killed in violence in the past two days. For the second year running, insurgent attacks shattered the commemoration of Ashoura, the holiest day of the Shiite religious calendar, but the violence produced a significantly smaller death toll than the 181 killed in twin bombings in Baghdad and the holy city of Karbala a year ago. The dead this year included a U.S. soldier who was killed in Baghdad when American troops responded to calls for assistance from Iraqi forces unable to cope with a slew of attacks, the Associated Press reported.--SPA1300 Local Time 1000 GMT www.spa.gov.sa/240828
