ISI solved it (FATA militants to blame for attack) but Zardari and Bhutto's supporters won't be happy until ISI or anyone else arrives at the conclusion they have already made.
mAD_Scientist...the mystery is yet unsolved but the main suspect is ISI itself sepecially after Benazir had said she would allow US to question Abdul Qadeer Khan and will flush AL-Qaueda...There are a lot of Al-Qaueda sypmpatheizers within Pakistani military establishment and some middle rank military officers even have family relations with Al-Qaueda...This is what Strait Times has reported ...
