Turkey's state-run news agency says the country's communications authority has imposed a 150,000 Turkish Lira (US$51,000) fine on Twitter for failing to remove content it said praised terror and incited violence.

Anadolu Agency said Friday that the Information and Communication Technologies Authority imposed the fine, accusing Twitter of publishing content that praised terror, made Turkey's security forces a target for attacks and incited hatred and violence, despite repeated warnings.

There was no more detailed information on the offending content. Officials at the authority could not immediately be reached for comment.

In April, Turkey temporarily blocked access to Twitter and other social media sites over the publication of photos showing a militant pointing a gun at a prosecutor who was killed in a failed hostage rescue operation.
