A Pakistani political party revealed on Wednesday what it said was the name of the CIA's highest-ranking officer in the country in protest of a CIA drone strike last week that killed as many as six people and prompted allegations that the agency had attacked a religious school.

The disclosure follows two previous instances in which the identity of a CIA station chief in Islamabad has been exposed, underscoring the constant friction that has come to characterize the two countries' counterterrorism partnership.

The purported name of the current station chief was included in a letter urging Pakistani police in the district where the latest drone strike occurred to pursue charges against CIA officers in the country as well as the agency's director, John Brennan.
