YouTube is banned in Turkey because of the video about Turkish possible military action in Syria

Turkish Prime Minister Tayyip Erdogan on Thursday denounced as "villainous" the leaking of a recording of top security officials discussing possible military action in Syria to the video-sharing site YouTube. Reuters news agency writes about this.

Turkish authorities ordered the shutdown of the site.

Turkish foreign minister Ahmet Davutoglu called the posting a "declaration of war," an apparent reference to an escalating power struggle between Erdogan and rivals.

The anonymous posting was an audio file with photographs of the officials involved.

It followed similar releases on social media in recent weeks that Erdogan has cast as a plot by his political enemies, particularly a Turkish Islamic cleric based in the United States, to unseat him ahead of March 30 elections.

The posting took the campaign to a higher level, impinging on a highly sensitive top-level meeting of security officials.

"They even leaked a national security meeting," Erdogan said at a campaign rally. "This is villainous, this is dishonesty ... Who are you serving by doing audio surveillance of such an important meeting?"

Reuters could not verify the authenticity of the recording.

The account posted what it presented as a recording of intelligence chief Hakan Fidan discussing possible military operations in Syria with Davutoglu, Deputy Chief of military Staff Yasar Guler and other senior officials.

Speaking to reporters in Kutahya, Davutoglu confirmed the meeting took place and said, "A cyber attack has been carried out against the Turkish Republic, our state and our valued nation. This is a clear declaration of war against the Turkish state and our nation."

Turkish authorities said they had taken an "administrative measure" to impose a block on YouTube, a week after they blocked access to microblogging site Twitter.

The foreign ministry said the recording was of a crisis management meeting to discuss threats stemming from clashes in Syria and that elements of the recording had been manipulated. The leakers would face heavy punishment, it said.
