government satellites. The images showed that Puthukkudiyiruppu Hospital had been heavily damaged between 28 January 2009 and 16 March 2009. Video On 25 August 2009 Britain's Channel 4 News broadcast mobile phone video of gunmen alleged to be Sri Lankan soldiers apparently summarily executing eight bound and blindfolded Tamil men at point-blank range in January 2009. The video was alleged to have been taken by a Sri Lankan government soldier and to have been circulating amongst soldiers before Journalists for Democracy in Sri Lanka, a group of exiled Sri Lankan journalists, obtained it. The Sri Lankan government rejected the video footage, calling it a fabrication. It established a four-member panel of Sri Lankan experts (Siri Hewawitharana, Chatura Ranjan de Silva, Brigadier Prasad Samarasinghe and Major P. A. Bandara) to investigate the authenticity of the video. This panel produced a technical analysis of the video in early September which concluded that the video was fake. An investigation by a UN commissioned panel of independent experts (Peter Diaczuk, Daniel Spitz and Jeff Spivack) found that the video was authentic. In a point-by-point repudiation of the Sri Lankan government's assessment, the experts concluded that the reaction and movement of the victims' bodies and blood evidence were consistent with being shot; the movement of the weapon and the shooter and the gases expelled from the muzzle were consistent with live ammunition firing, not blank cartridges; there was no evidence of breaks in continuity in the video, no additional video layers; and no evidence of image manipulation; and that video had been filmed on a mobile phone, not a camcorder, as the Sri Lankan government's analysis had maintained. The experts were unable to explain the movement of certain victims in the video, 17 frames at the end of the video and the date of 17 July 2009 encoded in the video (the conflict was officially declared over in May 2009) but this did not invalidate its authenticity. The independent experts' findings led Philip Alston, UN Special Rapporteur on extrajudicial, summary or arbitrary executions, to call for "an independent inquiry to carry out an impartial investigation into war crimes and other grave violations of international humanitarian and human rights law allegedly committed in Sri Lanka."
