Iran has banned The Economist magazine for describing the Persian Gulf as merely "the Gulf" in a map published in the latest edition, state television reported late Wednesday. It is the second time in two years that Iran has prohibited a publication of international repute for failing to use the term "Persian Gulf" in its maps. In November 2004, it banned the National Geographic atlas when a new edition appeared with the term "Arabian Gulf" in parenthesis beside the more commonly used Persian Gulf. Tehran believes in aggressively defending the historical term "Persian Gulf" against "Arabian Gulf," which it regards as a name dreamed up by Arab nationalists. While Iran dominates the eastern side of the waterway, the western shores are held by Arab countries.
