According to U.S. Central Command, the United States and its allies have carried out more than 340 airstrikes in Iraq and Syria as of Monday, about 70 percent of them in Iraq. Apart from eight strikes aimed at the Khorasan group, all of the strikes targeted the Islamic State. Central Command says the airstrikes hit combat positions, training camps and arms caches and destroyed or damaged more than 300 vehicles, including dozens of U.S.-built Humvees taken by the Islamic State from Iraqi forces. Central Command also said it has begun flying helicopters in Iraq for the first time as part the campaign. The step could put U.S. troops at risk of fire from militants on the ground.
