ran appears to have blocked the official website for the London 2012 Olympic Games.
Users in Iran have tweeted that they are unable to connect to london2012.com and are instead redirected to peyvandha.ir – a site offering stories from Iran’s official news agencies.
The blockediniran.com website confirms that most users in Iran are unlikely to be able to see the Olympics web pages.
Iran’s ministry of foreign affairs did not reply to a request for comment.
Nima Akbarpour, the presenter of the BBC’s Click Farsi programme, said such website bans are not uncommon, but it is hard to know exactly who is responsible.
