Nepal has said it would block access to several social media platforms, including Facebook, after they failed to register with authorities in a crackdown on misuse.

The government says users with fake IDs are spreading hatred and rumors, committing cyber crime, and disturbing social harmony via some platforms in a nation where 90% of the 30 million population use the internet.

It had given companies until Wednesday to register with the Ministry of Communications and Information Technology and name a local contact, grievance handler and person responsible for self-regulation — or face being shut down.
