Turkish prosecutors launch probe into 2 US attorneys
Gold trader Reza Zarrab, 34, has been charged in the U.S. for evading sanctions on Iran. An executive of Turkey's state-owned Halkbank and a former Turkish economy minister have also been indicted.
Turkish officials have accused Bharara of links to U.S.-based Muslim cleric Fethullah Gulen, whom Turkey blames for last summer's failed coup. Gulen denies the allegations.
