Supporters of Mir Hussein Moussavi, the presidential challenger whom President Ahmedinejad claims to have defeated with 63.4 per cent of the vote, have emulated the internet campaign techniques used by Barack Obama to appeal to the young generation of Iranians who make up the majority of his support base.
But reports from Tehran say that social networking websites such as Facebook and Twitter, the micro-blogging website, were taken down after Mr Ahmadinejad claimed victory. SMS text messaging, a preferred medium of communication for young Iranians, has also been disabled. This is widely suspected to be the result of government interference, but could equally be caused by the poor quality of the network and the heavy demand it is experiencing.
If Iran has shut down Twitter, why are so many pro-Mousavi tweets flooding twitter right now?
