The Islamic State group claimed responsibility for gun and car bomb attacks that killed at least 60 people Thursday in southern Iraq.
More than 80 other people were wounded in the attacks near Nasiriyah, the capital of Dhiqar province, officials said.
Militants opened fire at a restaurant, and shortly afterward a suicide attack carried out by a driver in an explosives-laden vehicle struck a nearby security checkpoint, officers said.
Three of the dead were police officers, while a number of others were Iranians, many of them pilgrims dining at the restaurant while en route to visit religious shrines.
In its statement claiming responsibility for the attack, Islamic State said it had killed "dozens" of Shi'ites.
Shi'ite-dominated Dhiqar province is 320 kilometers (200 miles) southeast of Baghdad.
