North Korea blocks Facebook, Twitter and Youtube

 

North Korea has announced that it is blocking Facebook, YouTube, Twitter and South Korean websites in a move underscoring its concern with the spread of online information. 

An announcement by ministry of posts and telecommunications was posted this week at the country's main mobile service provider, Koryolink, and other places serving internet users. 

Very few North Koreans have internet access. Typically they can see only a sealed-off, government-sanctioned intranet.
