The blast occurred despite intense security measures put in place across Iraq in the lead up to Sunday´s parliamentary vote, which has already been marked by violent attacks in Baghdad and the restive city of Baquba.[break]
A local official said the bomb exploded about 500 metres (yards) from the shrine to Imam Ali, son-in-law of the Prophet Mohammed and one of Shiite Islam´s most revered figures.
Of those injured, 33 were Iranian pilgrims, according to a medic at the Hakim hospital.
Thousands of Shiite Muslims visit the shrine to Imam Ali every month, many who make the pilgrimage from neighbouring Iran.
