Footage has emerged which appears to show an honorific incident in northern Syria.
The pictures are believed to show the aftermath of an incendiary bomb being dropped on a school playground, leaving scores of children and adults with napalm-like burns over their bodies.
The BBC has published footage of the injured being treated for severe burns after the attack which they report killed 10 pupils and left many more seriously injured. Reuters have also sourced similar images of what is believed to be the same attack which were taken on Monday.
Footage showed adults and children, their clothes burned from their bodies, being treated on the floor of a basic hospital.
Many were badly burned and could be seen shaking uncontrollably and left caked in a white substance.
A British medic, Dr Rola, who was in Syria with the charity Hand In Hand, treated the victims at the hospital told the reporters: "It is just absolute chaos and carnage here. We have had a massive influx of what looks like serious burns, seems like it must be some sort of, not really sure, maybe napalm, something similar to that.
"But obviously within the chaos of the situation it is very difficult to know exactly what is going on."
ITV News has not been able to independently verify either report.
Human Rights Watch have said that while they have not investigated this incident they have recorded several incidences of incendiary weapons in Syria since November last year.
