Pakistan's army on Thursday rejected as "negative propaganda" suggestions that it was not doing enough to combat al Qaeda and Taliban, hours after the top U.S. military officer accused its main intelligence agency of maintaining ties with militants. The comments reflected deepening mistrust between the two uneasy allies, whose relations hit a new low after fatal shooting of two Pakistanis by Raymond Davis, a CIA contractor, in January in the city of Lahore. "The Pakistan army's ongoing operations are a testimony of our national resolve to defeat terrorism," a military statement quoted army chief General Ashfaq Kayani as telling Admiral Mike Mullen, chairman of the U.S. Military's Joint Chiefs of Staff, during his fleeting visit to Pakistan on Wednesday. "He (Kayani) strongly rejected negative propaganda of Pakistan not doing enough and Pakistan army's lack of clarity on the way forward."
