North Korea's main government website has begun making it easier for readers to redistribute its criticisms of the U.S. and South Korea through Facebook, Twitter and South Korean micro-blogging services.

South Korea's Yonhap news agency, which monitors the North's media, reported Monday on the appearance of icons linking to the popular social networking websites.

Pyongyang strictly restricts Internet access by its own people, but uses the worldwide web extensively for overseas propaganda.

South Korean authorities ban websites containing communist information, but some people still manage to access sites in the Stalinist North.
