A tanker truck has blown up at a police check point in the Hilla province, south of Baghdad, killing or wounding at least 60 people, according to an Iraqi security official.
More than 60 people were taken from the bombing scene to nearby hospitals on Sunday, said Falah al-Radhi, head of the provincial security committee, without saying how many were killed.
“It’s the largest bombing in the Hilla province to date,” he said
Most of the dead were civilians, the rest police, one report states.
The attack happened shortly after noon local time (0900 GMT) while dozens of cars were at the checkpoint.
Iraq has seen a rise in violence in the past month, with suicide attacks killing more than 100 people.
Most recent attacks have been carried out by so-called Islamic State, but the group is not thought to hold territory south of Baghdad.
Fifty people were killed and more than 150 injured in a suicide bombing at a checkpoint on the outskirts of Hilla in March 2014.
