Iraqi Security Forces (ISF) have quickly captured critical infrastructure points in Iraq's Kirkuk province and in the surrounding areas. After beginning its operation overnight Oct. 15, the Iraqi military has reportedly taken control of the North Oil Company and North Gas Company headquarters, Kurdistan's K1 military base, the Bai Hassan oil field and the Baba Gurgur and Avanah domes of the Kirkuk oil field. Currently, the Kurdish Democratic Party (KDP) claims to still hold some of the oil fields in the area. The Iraqi government's purpose for the operation is to reassert federal control over the disputed province of Kirkuk's most strategic assets, which fell under the control of the Kurdish peshmerga after the Islamic State rose to power there in 2014.
