REUTERS/Ako RasheedBAGHDAD (Reuters) - Iraqi government forces took control of "vast areas" in the region of Kirkuk, including oilfields west of the city, in the early hours of Monday, Iraqi state TV said, but the Kurdistan Regional Government (KRG) disputed the assertions. Iraqi Prime Minister Haider al-Abadi ordered security forces "to impose security in Kirkuk in cooperation with the population of the city and the Peshmerga", the TV reports said. The elite, U.S.-trained "Counter Terrorism Service, the 9th armored division and Federal Police have taken control of vast areas of Kirkuk without confrontations", it said, and oilfields and Kurdish military positions were captured. However, a KRG security official denied that Iraqi forces were able to get closer to the city or take territory from the Kurdish Peshmerga fighters. The official told Reuters the oilfields and the air base west of Kirkuk were still under Kurdish control. The U.S.
