North Korea's main state newspaper warned on Tuesday of the "negative impact" from mobile phones use around the world, as both legal and illicit communications devices proliferate in the isolated country.

Rodong Sinmun published an article citing a ban on phones in classrooms in France and reports of technology-enabled cheating in India and argued that mobile devices were spreading "decadent and reactionary ideological culture."

"Erotic notices, fictions and videos, as well as violent electronic games, are spreading through the mobile phones without limits," the newspaper wrote.
