(AP Photo/Eric Gay, File) (Newser) – Iran fired at a US drone last week because it was spying on off-shore oil tankers in Iranian airspace, according to an Iranian Revolutionary Guard commander. Amir Ali Hajizadeh told a quasi-official news agency today that the drone flew too close to Kharg Island in the Strait of Hormuz: "It was gathering economic information and intelligence on Kharg Island and oil tankers," he said. "If this is repeated, we will definitely react." The Pentagon said the drone was in international airspace when a Russian-made warplane from Iran shot at it and missed.
