Pakistan on Wednesday hit out angrily at a leaked NATO report accusing its security services of secretly aiding the Afghan Taliban, calling it "frivolous" and "not worth commenting on".
"This is frivolous, to put it mildly. We are committed to non-interference in Afghanistan and expect all other states to strictly adhere to this principle," foreign ministry spokesman Abdul Basit told AFP.
A senior security official condemned the leak, as reported by the BBC, which also broadcast a documentary "Secret Pakistan" last year accusing parts of Pakistan's intelligence service of complicity with Taliban militants.
"The report is not available, leaks not worth commenting," he told AFP.
Pakistan's Foreign Minister Hina Rabbani Khar was on Wednesday due to hold talks with Afghan President Hamid Karza in Kabul, which had been billed as an effort to get notoriously frosty relations back on track.
"We are also committed to an Afghan-led and Afghan-owned reconciliation process," Basit said.
"Pakistan has suffered enormously because of the long conflict in Afghanistan. A stable and peaceful Afghanistan is in our own interest and we are very much cognisant of this".
