Syria crisis: Incendiary bomb victims 'like the walking dead'

A BBC team inside Syria filming for Panorama has witnessed the aftermath of a fresh horrific incident - an incendiary bomb dropped on to a school playground in the north of the country - which has left scores of children with napalm-like burns over their bodies.

Eyewitnesses describe a fighter jet dropping the device, a low explosion, followed by columns of fire and smoke.

Ian Pannell and cameraman Darren Conway's report contains images viewers may find extremely distressing.
