In pictures: 'Hercules' footage

1 of 6 The MoD has refused to comment on the authenticity of the video aired by al-Jazeera, purportedly from insurgents claiming they shot down an RAF Hercules which crashed in Iraq.

2 of 6 The footage did not show missiles actually hitting a plane, and it was not certain that the wreckage was that of a Hercules C-130.

3 of 6 Before the video was aired, Defence Secretary Geoff Hoon said: "We are aware of reports that the aircraft may have been shot down but we are not in a position to come to any conclusions until the investigation is complete."

4 of 6 Air Chief Marshal Sir Jock Stirrup, the RAF's chief of air staff, said he had "no evidence at all" to dispute or confirm the claims in the video.

5 of 6 A spokesman for al-Jazeera said the video came from a faction of the 1920 Revolution Brigade, a group named after the uprising against the British after World War I.
