Syria crisis: BBC crew returns to Aleppo
The brutal conflict in Syria has claimed the lives of thousands of civilians and displaced millions, in and outside the country.
Last month the BBC reported on an attack on a school in Syria when an incendiary bomb with 'napalm-like substance' was dropped on the playground.
A team working for Panorama witnessed the aftermath of the incident as children with terrible burns were rushed to hospital.
They have returned to Syria to see the progress of some of the victims who suffered burns.
Reporter Ian Pannell and cameraman Darren Conway's report contains distressing scenes.
