14 June 2011. The special features films shot during the last stages of the war that appear to show the shelling of areas in the no-fire zone and the aftermath, executions of captured LTTE combatants and dead female Tamil fighters being loaded on to a truck. Videos used in the first half were shot by individuals in the no-fire zone while the latter half seemingly shows mobile phone footage shot by the Sri Lankan soldiers. The same program was broadcast in Australia on ABC TV 4 Corners program on 4 July 2011 presenting allegations that up to 40,000 Tamil civilians were killed by shelling or executions after surrender in many cases after being sexually abused.

Ofcom investigated Channel 4's documentary after more than 100 complaints were received saying that it was misleading and misrepresentative. However, Ofcom later found the documentary to be 'not in breach' of any regulations. In a technical analysis of the mobile phone footage on behalf of Sri Lanka's Lessons Learnt and Reconciliation Commission, E. A. Yfantis, a professor of computer science at University of Nevada-Las Vegas specialising in computer graphics and image processing, stated that "based on mathematical analysis, blood in the 3GP videos is not real blood. It is not clear if the blood in the 3GP scenes is water with red dye or digitally constructed or edited video blood" and that "videographic and mathematical analysis of the two 3GP videos show that the videos either were edited, or staged, or both". He concluded that "Careful analysis of the two 3GP videos which included both frame by frame visual inspection as well as the robust mathematical attributes of the video frames, has led us to the conclusion that this is a very deliberate and orchestrated video". The report also detailed the fact that the video file was named "produce.3gp", suggesting that the video file may have been a result
