U.S. Airdrops Begin In Iraq

(Undated) -- Relief supplies from the United States are now being air-dropped into northern Iraq. Food and water are being delivered to thousands of refugees who are trapped on a mountain after fleeing from Islamist militants. However, there are so far no signs of any U.S. airstrikes to stop the advance of Islamic State fighters. President Obama says he authorized the limited bombing to prevent "genocide" and stop the onslaught of Sunni radicals.
