Imran Khan's party 'outs' CIA chief in Pakistan The letter, written in English by PTI information secretary Shireen Mazari, requested that the Islamabad station chief and CIA Director John O. Brennan be charged with "the gross offences of committing murder and waging war against Pakistan." The call relates to a Nov 21 drone strike in the country's lawless northwest which hit a religious seminary, killing five militants including senior commanders of the Taliban-linked Haqqani Network. The PTI's move comes amid increasing discontent over US drone strikes in Pakistan. The government was angered by the attack earlier this month which killed the head of the Pakistani Taliban, Hakimullah Mehsud, complaining that his death derailed efforts to hold peace negotiations with the group and other militant organisations. Khan has campaigned vehemently against the use of drones, arguing they only generate further radicalisation and terrorism. He was particularly infuriated by the Nov 21 attack, regarded as especially provocative as it fell outside the Federally Administered Tribal Areas where most strikes have been directed, in the province of Khyber Pakhtunkhwa where his PTI heads the local government.
