Two bomb attacks have killed at least 14 Shia pilgrims and injured 40 others in the city of Karbala in central Iraq.
A suicide bomber riding a motorcycle set off one of the blasts on Wednesday, Iraqi police sources told Al Jazeera.
Some of the injured were being taken to hospitals in the city of Najaf, about 72km away, police said.
Thousand of Shia have been travelling to the city for their religious rite.
Earlier on Wednesday, at least 1 person was killed and 6 others injured in two separate blasts in Baghdad.
On Monday, at least 54 people were killed and more than 100 injured in an attack by a suspected female suicide bomber in Baghdad, an interior ministry official said.
That attack took place amid a procession by Shia who were on a pilgrimage to Karbala, 80km southwest of the Iraqi capital.
Thousands of troops and police have been deployed to protect worshippers as they walk towards the Imam Hussein shrine.
