Iraqi government forces have captured key installations outside the disputed city of Kirkuk from Kurdish fighters، BBC reported. A military statement said units had taken control of the K1 military base، the Baba Gurgur oil and gas field، and a state-owned oil company's offices. Baghdad said the Peshmerga had withdrawn "without fighting"، but clashes were reported south of Kirkuk. The operation was launched a month after the Kurdistan Region held a controversial independence referendum. Iraq's prime minister has said the vote - in which residents of Kurdish-controlled areas، including Kirkuk، overwhelmingly backed secession - was unconstitutional. The Kurdistan Regional Government (KRG) insisted it was legitimate. US officials said they were "engaged with all parties in Iraq to de-escalate tension".
