How both US and Russia manufactured news for the Syria war

Of course, all sides who engage in propaganda engage in spreading false news.  Remember the propaganda of false news by US occupiers in Afghanistan?  Syrian regime and Syrian rebels have both been engaged in spreading false news, as have the Qatari and Saudi and Iranian regime media.  It has been a festival.  US PR firms have also been involved in intense propaganda efforts which included fake news.  This story was clearly one of many false news stories inserted by the propagandists of the US in Western and Arab media.
