The head of the Syrian National Congress (SNC), Ahmed Moaz al-Khatib, has resigned from the opposition movement, according to a statement on his Facebook page.
Al-Khatib said he resigned because he wanted to work without the constraints that being part of an institution placed on him.
"I announce my resignation from the National Coalition, so that I can work with a freedom that cannot possibly be had in an official institution," he said in the statement.
"For the past two years, we have been slaughtered by an unprecedentedly vicious regime, while the world has looked on," Mr Khatib added.
"All the destruction of Syria's infrastructure, the detention of tens of thousands of people, the forced flight of hundreds of thousands and other forms of suffering have been insufficient for the international community to take a decision to allow the people to defend themselves."
