The General Director of Al-Jazeera, Mustafa Sawak, said that some parties provided the satellite channel with false news about the Arab revolution to harm the channel's credibility. Sawak said that most of the criticisms Al-Jazeera received are irrelevant, as the channel never presented false news, but some parties intended to mislead the channel. Sawak is Algerian. He was previously the director of Al-Jazeera London office before becoming the director of Al-Jazeera Center for Studies.
