President Obama has dismissed the idea that supplying US arms to Syrian rebels would have toppled President Assad, calling it a "fantasy".
His comments came in a CBS interview when he was asked if a power vacuum had been created in the Middle East which was fuelling violence in Iraq.
He said there was no "ready-made moderate Syrian force that was able to defeat Assad".
