In light of recent revelations surrounding the 2012 kidnapping of NBC Chief Foreign Correspondent Richard Engel, NBC’s reporting of the Aleppo “playground napalm bomb” of 26 August 2013 warrants scrutiny.
A girl who witnessed the attack told NBC News’ Richard Engel that the plane attacked the school twice.
“As we were going inside the classroom, it hit again. I didn’t hear anything. We just saw people burning,” said the student, who was not identified. “My classmates were burning. It felt like Judgment Day.”
However as noted here the words of the unidentified “student” who “told” her story to Engel appear to be directly lifted from this You Tube video, shot at Atareb Hospital on the evening of 26 August 2013 (the most strikingly similar sections are italicised):
… while escaping they called us to return to the school as the war-plane has not finished bombing yet .. they were sure that it will bomb again .. and then the war-plane bombed us .. I did not hear any sound but all what I saw is people burning .. I got burnt and so my friends .. we did not know what happened and why .. a war-plane bombed us and bodies in flames all over the place .. I felt like it is the judgement day.  
Wider questions regarding the authenticity of this video are discussed here.
The NBC article is also noteworthy in that it cites the contemporary assessment (“days after the attack”) of Dr Rola (“Roula”) Hallam that the seven month old infant who in most accounts is claimed to be the first victim received at Atareb Hospital “was covered in full-body burns”.
