An Iranian rapper has been issued with fatwas and faced death threats after releasing a controversial song. Shahin Najafi, an Iranian singer based in Germany, released a song containing references to one of the 12 Shia Muslim Imams. The song, which was posted on YouTube, offended some who claim it insults their beliefs, while others claim the song breaks taboos on expressing views about religious personalities. A religious Iranian website has offered a reward of $100,000 (£62,000) for anyone who kills the rapper.
