People may remember that teenage girl weeping for the cameras, as she described seeing Iraqi soldiers dumping newborn babies from incubators in a Kuweit hospital, to steal the incubators, during the 1990 invasion. Even George Bush (the 1st) repeated that one over and over, in phony indignation.  Turned out the girl lived in the USA, and was the daughter of the Kuwait ambassador. Even Amnesty International fell for the hoax thereby losing much credibility. Two years later they had to apologise.  

Friends, I really don't know if this Bana girl is in Aleppo or in the UK as part of some MI-6 propaganda. But it is well worth being skeptical. I note that all major Canadian media treat the story as real (as they did the incubator story), while their comments sections express varying degrees of skepticism - surely a healthy vaccine against media lies.
