U.S. forces have conducted four more airstrikes against Islamic militants in Iraq, hours after President Obama declined to set a firm timetable for the latest U.S. military campaign in Iraq on Saturday.
The airstrikes took place in the area of Sinjar, in the northwest part of the country, where militants were firing on Yazidi civilians taking shelter in the Sinjar mountains.
The U.S. Central Command said that the strikes, which took place in the late morning and midafternoon EDT, had destroyed several armored personnel carriers and armed trucks.
Earlier in the day, the U.S. launched a new airdrop of food and water for thousands of refugees trapped in Iraq's Sinjar mountains.
Pentagon spokesman Rear Adm. John Kirby said three planes dropped 72 bundles of supplies for the refugees, including aid for more than 28,000 meals and more than 1,500 gallons of water.
In the first, at approximately 10 a.m., a U.S. drone struck a terrorist mortar position, Kirby said in a statement.
"When ISIL fighters returned to the site moments later, the terrorists were attacked again and successfully eliminated," he added.
At approximately 11:20 a.m. in the second strike, four F-18/A fighter jets hit a stationary ISIS convoy of seven vehicles and a mortar position in two passes also near Erbil.
"On both runs, each aircraft dropped one laser guided bomb making a total of eight bombs dropped on target, neutralizing the mortar and convoy," Kirby said.
President Obama announced on Thursday that he had authorized the military to carry out targeted airstrikes and drop humanitarian supplies to aid Kurdish fighters and refugees under attack from ISIS.
Earlier Friday, a pair of F/A-18 fighter jets dropped 500-pound laser-guided bombs on a mobile artillery piece near Erbil.
The artillery was being used to shell Kurdish forces defending the city, where some U.S. military personnel are currently stationed.
