Unrest began in Ahvaz on 15 April 2005 after a letter began circulating that week, attributed to an adviser in the office of Iranian President Mohammad Khatami, proposing measures to reduce the proportion of Arabs in Khuzestan; the letter's authenticity was denied by the government and disputed among analysts.[2]
