Iran officials find wreckage of deadly plane crash

Iran has suffered several plane crashes in recent decades. Tehran blames U.S. sanctions for preventing it from importing new aircraft or spare parts. A Boeing 727 crashed in northwest Iran in 2011, killing 78 people, and in 2009 all 168 people on board died when a Caspian Airlines Tupolev crashed en route for Armenia. In 2003 an Ilyushin-76 troop carrier crashed in southeast Iran, killing all 276 Revolutionary Guard soldiers and crew.
