The armed forces have captured a U.S. spy drone over the Persian Gulf waters. The Islamic Revolution Guard's Corps says its radars spotted the scan eagle drone after it intruded into Iranian airspace. The Commander of IRGC's naval forces, Rear Admiral Ali Fadavi, said such drones are usually launched from giant airplane carriers. This last month, IRGC fighter jets intercepted another intruding U.S. aircraft, forcing it to leave Iran's airspace. And almost a year ago, the Iranian military captured an advanced U.S. stealth drone on a spy mission, some 220 kilometers inside the country near the border with Afghanistan. In a letter that was sent to the UN Secretary-General Banking Moon, the UN asserted at that point that the U.S. had violated Iranian airspace with its drone flights. But in particular, in the past month, this particular incident was repeated in scope just about a month ago, or maybe a little over a month ago, of which a U.S. drone came into Iranian territory and it was chased away by Iranian fighter jets. And then another case of a U.S. drone being captured and brought down was back in December of 2011, in which the Iranian air force was able to bring the U.S. drone down. This was around the Afghan border of which it was cited that the U.S. drone was spying on Iranian territory.
