Re: Militants kill 30 troops in Pak fort capture

I understand that, but Tribals are not doing this though (Even according to Musharraf and Co.). It's the certain group that is committing all these acts.

I always thought tribals live in North & South Waziristan. Who else lives there then?? Why do tribals allow them to live there??
