Asked if the steps could include shutting those sites down, Erdogan replied: "That included. Because these people or institutions are (using social media) for all kinds of immorality, all kinds of espionage and spying."
But President Abdullah Gul, who carries moral authority in Turkey, dismissed Erdogan's idea on Friday, saying shutting down social media was out of the question.
Erdogan this week acknowledged some of the leaked recordings, including two where he is heard meddling in a court case against a media proprietor and in a tender for the construction of warships. He has rejected as "fabrication" recordings purported to be of Erdogan instructing his son to dispose of large amounts of money on the day when prosecutors and police carried out raids on the homes of three former ministers' sons as part of a corruption and bribery investigation.
Erdogan, claiming to be a victim of a Gulen-orchestrated plot, has taken a series of steps to stall the corruption investigation, including removing hundreds of police officers and prosecutors and expanding government controls over the judiciary and the Internet. The Internet restrictions sparked violent protests in Istanbul.
