Spate of suicide attacks in Iraq kill at least 51

Three women bombers blew themselves up on Monday in a crowd of Shiite pilgrims in Baghdad, one of a string of attacks in Iraq that killed at least 51 people, undermining hopes of a drop in violence.

Scores of people were also wounded in the attacks, which follow a relative lull in the sectarian violence that has ravaged the country since February 2006, when insurgents blew up a Shiite mosque in the central city of Samarra.
