Razor wires surround what looks like a prison camp. Thousands of Tamil civilians have been moved to so-called 'relief villages'. "'I would be very careful about talking to people here because it could mean trouble for them,"' an MSF worker warns us. Although they are officially refugees, Tamil civilians are considered potential terrorists and are not free to leave. As the government tightens its control over the press, no independent journalists are allowed near the frontline. '"You have to remember we are fighting with the largest terrorist group in the world,"' says the Defence Secretary.
