A terrorist attack on the Bai Hassan oilfield in Kirkuk early on Wednesday has caused casualties and damage.
A statement from the Ministry of Oil said that wells 177 and 183 were bombed, and "a number of security forces and energy police were killed and wounded".
The safety and firefighting teams from the North Oil Company (NOC) and the supporting authorities were able to quickly extinguish the fire at well 177, but were still working to control the fire of well 183.
Sources told Reuters that production was not affected.
It's the second attack on the facility in less than a month; a bomb in April did not result in damage or injury.
