TEHRAN — Iran claimed Sunday it made well on its promise and has copied a United States drone it captured in December 2011 — and state television broadcasted images that allegedly show the drone copy. Tehran captured the U.S. RQ-170 Sentinel oven Iranian airspace, apparently spying on the country's nuclear sites. The Iranian TV broadcast showed supreme leader Ayatollah Ali Khamenei's visit to the Revolutionary Guards air wing exhibition on Iran's military advances, of which drones and ballistic missiles were highlighted and footage showed two nearly identical drones.
