N Korea 'puts block on Instagram'
Warnings are appearing on Instagram accounts in North Korea that claim access to the popular photo-sharing app is being denied and the site blacklisted for harmful content.
Opening the app with mobile devices on the North Korean carrier Koryolink has resulted in a notification in English saying: "Warning! You can't connect to this website because it's in blacklist site."
A similar notice in Korean says the site contains harmful content, though that is not mentioned in the English version.
