I listened to a media report / discussion on who they are on a local tv channel.
The reason of their retiliation is because they were ignored especially by the previous government. Despite all, they should have tried to talk to the government through somebody, not start killing other innocents of their own country.
Besides, I believe there are now steps taken by some responsible and authoritative figures in the Pak government to imrpove their situation and make them a part of Pak by giving them equal opportunities, just like other Pakistanis. Hopefully, these steps will bring out the best in our pakhtun brothers so that they can contribute to the development and welfare of Pakistan and become one of the strongest assets of Pakistan (InshaAllah) instead of turning into rebels and harm their own land.
But I thought they were CIA agents? lol
