According to leaked Iraq war logs, “Iran is reported on 17 November 2006 to be offering new techniques to suicide bombers in Iraq. Instructors in Tehran explain how miniature cameras can be installed in a suicide vest to allow a controller to monitor the movements of the bomber towards the target. If the bomber fails to detonate his vest the observer can do it remotely. The intelligence report says Syria is engaged in the same process, sometimes rigging surplus US military uniforms with the tiny cameras. The report gives no source, nor does it say whether any such vests or coats have actually been found by western forces or officials.”
