Iraq Insurgents Promise More fighting

(Tikrit, Iraq) -- Insurgents in Iraq promise more fighting after taking control of two cities. A recording believed to be from the al-Qaeda linked Islamic State of Iraq and Syria urges the militants to take the fight to more Iraqi cities, including Baghdad. Rebels now control the northern cities of Tikrit and Mosul , and are closing in on the country's biggest oil refinery. Meanwhile, Kurdish forces say they are fully in control of the oil-rich northern Iraq city of Kirkuk , after Iraqi army forces fled.
