Who knows? Nobody does. See my first post… I can also buy that since there are so many Taliban factions, it could be anyone…
But with such a corrupt govt. what can one expect? Its all very confusing… Surely the Talibans who already are criminals may really have done it, but just besides that, do any merceneries have a role? Neither you nor I know what the truth is… so we must not ignore what is going on and look at the complete picture.
