At least 60 people have been killed in a suicide attack in which an explosives-laden truck was blown up at an Iraqi police checkpoint.
The Islamic State group has claimed responsibility for Sunday's attack at the entrance to the city of Hilla, south of Baghdad.
Medical and security officials said at least 60 people died in the attack.
Islamic State claimed responsibility in a posting on the website of the Amaq news agency, which supports Islamic State.
Dozens of injured were taken to nearby hospitals, said Falah al-Radhi, head of the provincial security committee.
"It's the largest bombing in the province to date," he told Reuters.
"The checkpoint, the nearby police station were destroyed as well as some houses and dozens of cars."
Hilla is the capital of the province of Babylon, a predominantly Shi'ite region with some Sunni presence.
"A martyr's operation with a truck bomb hit the Babylon Ruins checkpoint at the entrance of the city of Hilla, killing and wounding dozens," the statement on the Amaq website said.
