According to the BBC’s Galpin, reporting for BBC Radio 4 (19/9/05, 18 hrs news script), Iraqi police sources in Basra “told the BBC the two British men were arrested after failing to stop at a checkpoint. There was an exchange of gunfire. The men were wearing traditional Arab clothing, and when the police eventually stopped them, they said they found explosives and weapons in their car… It’s widely believed the two British servicemen were operating undercover.” Undercover? Dressed as Arabs? What were they trying to do that had caught the attention of their colleagues, the Iraqi police?
