A British bombmaker is fighting for the Taliban against British troops in Afghanistan, it has been revealed.
DNA from a terror suspect with British nationality has been found on an unexploded roadside bomb planted by the Taliban.
The DNA sample was taken from an roadside bomb that was diffused by bomb disposal experts in Helmand Province.

'My brother was trying to help Muslim people. These bombers aren’t helping Afghans - they’re just making it worse for everyone.'
