IWPR
I have enormous respect for the work of the Institute for War and Peace Reporting. They work in conflict regions to teach the basic principles of journalism to local journalists, including citizen journalists. They really do get right in to the most difficult situations, and have access to knowledge on the ground that western media organisations often lack. I worked closely with their office in Tashkent, Uzbekistan, where Michael Andersen did a great job.
The fact that IWPR accesses direct first hand knowledge of what really happens during conflicts, almost certainly holds the key to the death of Jackie Sutton. She was killed for something she knew. The official Turkish story that she killed herself in the airport in despair at missing a connecting flight, is risible.
I cannot claim to any idea at present what it was she knew that caused her to be killed. It follows from that I do not know who killed her. But the speed of the Turkish authorities to promote a suicide narrative must in itself raise suspicions.
