Iran's new Communications Minister said today that negotiations are underway with Twitter to unblock the service, which has been banned for years despite being used even by the country's supreme leader. <br/><br/>The micro-blogging platform was barred at the time of mass anti-regime protests in 2009 that followed allegations of massive rigging in the re-election of President Mahmoud Ahmadinejad. <br/><br/>The 36-year-old Jahromi became Iran's youngest-ever minister this week, and the first to be born after the 1979 Islamic revolution. <br/><br/>His selection has been criticised by rights groups over his involvement in surveillance during and after the mass anti-regime protests of 2009. He rejected the criticism.
