Simple doubt, when the Iran border is so near why have camp inside pakistan? It would be a dead give away. It makes more sense to have it in afghanistan or Iran itself. If in case of Iran camp would be more secure. More ever the region mentioned "parachinar" seems to have a big road way cutting across meaning it has more chances of getting discovered.
