Turkey's communications regulator has imposed an unprecedented fine on Twitter for allowing the publication of content deemed to justify terror, the state-run Anatolia news agency said Friday. The Information and Communication Technologies Authority (BTK) has fined Twitter 150,000 lira ($50,700), the first time it has issued such a penalty to the company. Despite repeated warnings, Twitter failed to withdraw content "praising terrorism, targeting the security forces and inciting hatred and violence", it said.
