A pilot has died after his Sukhoi-22 jet fighter-bomber crashed in Iran’s south, the website of Irans Revolutionary Guard reported Saturday. The report on sepahnews.com said the plane was taking part in a morning exercise in southern Fars province when it crashed. The website did not give further details. Iran has a history of air accidents blamed on its aging aircraft and poor maintenance. Iran has both Russian-made and US-made fighter planes. The US aircraft were delivered to Tehran before the 1979 Revolution that ousted the western-backed monarchy. Iran purchased Sukhoi fighter-bombers from Russia after the revolution.
