A leading Russian Muslim cleric warned Thursday that fans who attend upcoming concerts by openly singer Elton John face divine punishment, after the star spoke out in support of Russian gays. “The only thing we can do as believers is to call the people not to give into the temptations of the devil and not attend Elton John’s Russian concerts,” Seidzhagfar Lutfullin, the imam of a mosque in the Volga city of Kazan told the Nezavisimaya Gazeta daily.
