Turkey's Prime Minister Tayyip Erdogan has said the nation could ban Facebook and YouTube, which he says have been abused by his political enemies, after local elections on March 30.
Erdogan is locked in a power struggle with the US-based Turkish cleric Fethullah Gulen, a former ally who he says is behind a stream of "fabricated" audio recordings posted on the internet allegedly revealing corruption in his inner circle.
"We are determined on this subject. We will not leave this nation at the mercy of YouTube and Facebook," Erdogan said.
He added that the possible barring of these sites was included in his planned measures.

The programme, called "Squeaky Dolphin", was able to monitor YouTube in real time, collect addresses and some other user information.
According to the “Psychology A New Kind of SIGDEV [Signals Development] presentation, the Government was also able to take part in “broad real-time monitoring of online activity” of URLs “liked” on Facebook, Blogspot/Blogger visits and Twitter.
A man who admitted posting online footage of himself dressed in a Ku Klux Klan costume to stir up racial hatred has been jailed for 12 months.
Christopher Philips appeared at Wolverhampton Crown Court today, after previously pleading guilty to appearing in three YouTube videos last year showing him wearing the klansman outfit, and posing with a life-sized golliwog doll at a far-right gathering.
Sentencing Philips, formerly known as Darren Clifft, Judge John Warner told him: "It does not require advanced education or knowledge of history to know what you were seeking to convey might cause offence."
He added the publication of the videos by Philips, who has Asperger's, would obviously be "thoroughly offensive" or "highly inflammatory", leaving him with no choice but to jail the 24-year-old.
