An explosion near Kirkuk in Iraq is said to have killed at least eight police officers on Sunday.
An explosion hit a police convoy near the village of Safra, 30 kilometres southwest of Kirkuk, wounding two policemen seriously, police sources said.
Police told AFP that the bombing was an ISIS attack, putting the initial toll at seven dead.
Police and other security forces are routinely targeted by ISIS in Iraq.
Terrorists have been able to exploit a security vacuum in the northern parts of Iraq that are not controlled by either Kurdish or federal security forces, which are both absent.
There have been several attacks in Kirkuk province, which is part of the disputed territories.
Five men, all believed to be Iraqi soldiers, were shot dead after attackers raided a desert checkpoint in Kirkuk last month.
