The Pakistani army on Thursday rejected what it called "negative propaganda" by the United States, hours after the top US military officer accused the country's spy agency of continued links to a powerful Afghan Taliban faction.
The unusually strident back and forth reflected the poor state of relations between the two counterterrorism allies, which sunk to new lows after an American CIA contractor in January shot and killed two Pakistanis he said were trying to rob him.
While officials from both nations have raised the level of rhetoric, they have also spoken of the need to keep the partnership intact. Washington needs Pakistani support, even if not as whole hearted as it would like, to be able to begin withdrawing troops from Afghanistan this summer, while Islamabad relies heavily on U.S civilian and military aid.
Adm. Mike Mullen, the chairman of the US joint chiefs of staff, said Wednesday he would bring up the issue of Pakistan's ties to the militant Haqqani network when he saw Pakistani army chief Gen. Ashfaq Parvez Kayani later the same day in Islamabad.
The Haqqani network is a largely independent Afghan Taliban faction with bases in Pakistan's North Waziristan tribal region just across the border from Afghanistan. It is considered one of the most lethal forces battling US and NATO troops in Afghanistan.
Pakistan's military-run Inter-Services Intelligence spy agency has links to the network's leaders that date back to the 1980s Soviet occupation of Afghanistan, when the group was also supported by Washington. But after the Sept. 11, 2001, attacks, Pakistan has insisted it has cut those ties.
Still, many analysts and US officials suspect Pakistan may be trying to maintain its links to the Haqqanis so that it can use them as a means of retaining influence in Afghanistan — and keeping a bulwark against archrival India — after the Americans leave.
"The ISI has a long-standing relationship with the Haqqani network, that doesn't mean everybody in the ISI but it's there ... I believe over time that has got to change," Mullen said in the GEO TV interview.
In a statement issued after he saw Mullen, Kayani did not mention the Haqqanis, and said both sides were determined to keep their relationship intact.
The statement said Kayani told Mullen that he "strongly rejects negative propaganda (about) Pakistan not doing enough".
He also said the army's multiple offensives against insurgent groups in the northwest are evidence of Pakistan's "national resolve to defeat terrorism."
Kayani also slammed the ongoing US missile strikes in Pakistan. Those strikes usually hit North Waziristan, where the Haqqanis are based and the one tribal region along the Afghan border where the army has not staged an offensive despite US pleas.
Pakistan has long denounced the drone-fired missile strikes as violations of its sovereignty, but it is widely believed to secretly cooperate with at least some of the attacks. But in mid-March, Kayani issued a rare statement denouncing one such attack after it killed nearly 40 people. A US official said the target was justified, but Kayani said dozens of innocent tribesmen died.
That strike came the day after the American CIA contractor Raymond Davis was released after compensation was paid to the families of the victims. The Davis case badly strained relations, with Pakistan refusing to take a stand on whether Davis had diplomatic immunity from prosecution as the US embassy claimed.
