Iranian government pursuing 'national internet'
Iranian internet users could have access to international websites such as Google and YouTube blocked, under little-known government plans to manage the internet.
The Iranian government says its "national internet", currently used for domestic websites including banks and government departments, would improve browsing speeds and data security.
But critics warn it could allow the government to cut off access to foreign sites, restricting access to information and preventing users from sharing information online.
