At least 20 Shia pilgrims have been killed in a bomb blast near the holy Iraqi city of Karbala, officials said.
Security chiefs said around 90 people were wounded in the blast from a device placed on a motorcycle.
The attack was the latest in a string of bombings this week that have targeted pilgrims making their way to an important Shia religious observance in Karbala.
The blasts have raised fears of a rise in attacks by suspected Sunni insurgents when the pilgrimage culminates on Friday.
The Press Association has contributed to the report.
