North Korea blocks Facebook & Twitter

North Korea has announced it is blocking social media platforms like Facebook, YouTube, Twitter and South Korean websites in a move underscoring its concern with the spread of online information.Very few North Koreans have internet access. Typically they can see only a sealed-off, government-sanctioned intranet. But foreigners had previously been able to surf the Web with almost no overt restrictions, though most likely with behind-the-scenes monitoring of their internet activities.The new restrictions will make it more difficult for visitors or the small community of foreign residents in North Korea to post real-time information about the country to the outside world, and will further limit the ability of North Koreans with internet access to view information about their country posted elsewhere.
