Turkey’s PM Recep Tayyip Erdogan says his government could ban Facebook and YouTube, arguing that opponents are using social media to attack him.
But President Abdullah Gul later called such a ban “out of the question”.
Allegations of corruption against Mr Erdogan have been repeated on the social media sites.
The leaks included a phone conversation in which, allegedly, he and his son discussed how to hide huge sums of money. Mr Erdogan called it a montage.
His Islamist-rooted AK Party faces key local elections on 30 March.
“We will not leave this nation at the mercy of YouTube and Facebook,” Mr Erdogan told the Turkish broadcaster ATV.
“We will take the necessary steps in the strongest way.” Asked if that could include barring the social media sites, he said: “Included.”
He said the two sites were being used for “all kinds of immorality, all kinds of espionage”.
