A group of leading Ukrainian journalists interrupted President Viktor Yanukovych's speech at a newspaper conference today to protest against government censorship.
About a dozen reporters rose from their seats and held up posters reading "Stop Censorship" and "Media Oligarchs Serve the Authorities," upsetting Mr Yanukovych's opening statement at the annual World Newspaper Congress.
State security guards surrounded the protesters, ripping posters out of their hands.
In his speech, Mr Yanukovych vowed to uphold democratic principles and media freedoms.
"The main task of the government in the media sphere ... is to create conditions when free press can develop freely and be independent of any kind of control," he said.
But investigative reporter Mustafa Nayem called Mr Yanukovych's words cynical lies.
He said: "It is not a secret to anyone that the media atmosphere under President Yanukovych has worsened drastically."
