Isil jihadists held a public screening of the video they shot of a Jordanian pilot being burned alive for a cheering crowd in their capital, the Syrian city of Raqqa, according to an activist group.
In footage of the incident, car horns are heard honking as the film is played on the screen, including the graphic images of Lt Moaz Kasaesbeh being led into a cage and consumed by the flames.
The crowd then shouts "God is Great". It is impossible to tell how many people attended and how many of those were ordinary citizens rather than jihadists.
However, one young boy who appears to be about eight or nine, is interviewed. He is smiling broadly as he says: "If he was here, I'd burn him with my own hands. I'd like to capture pilots and burn them."
The killing of the pilot was defended by the group as an "eye for an eye" punishment for his taking part in air raids against them.
Raqqa is Being Slaughtered Silently, the underground anti-Isil activist group that provides regular updates from inside the city, says the killing happened on a patch of waste ground near where a recent coalition air raid killed 30 female jihadists.
It said it worked out the location by comparing buildings and trees seen in the video with images taken from satellite photographs.
In one image, showing Lt Kasaesbeh being led into the cage where he was to die, a shadowy building can be seen in the background. The activists found a patch of waste ground similar to that where he was killed, with a similar building on the corner of a block.
They also identified trees seen in a similar shot taken from a different angle, and then what appears to be a lamppost.
In the final image they use, the distinctive breeze block wall which can be seen behind the cage is compared to a wall on the edge of the compound facing on to the waste ground.
The area is on the edge of the city, near the River Euphrates, which marks the southern border.
