WASHINGTON: The CIA and ISI , respectively US and Pakistani intelligence agencies, which were once joined at the hip during the Soviet occupation of Afghanistan, are now torn apart from head to heart.Ties between the two spook outfits have hit an all-time low after Pakistani media outlets leaked the name of the CIA station chief in Islamabad for the second time this year, as reported by Times of India last weekend, even as the two sides wrangled over the Raymond Davis episode.US officials said on Monday that they were not withdrawing their man in Islamabad as they did on the previous occasion when Pakistan outed the previous Islamabad station chief Jonathan Banks . Pakistan maintained that the leaked name (purportedly a "Mark Carlton") of his replacement was not the correct moniker."If we were going to release the name, we would release the right one," an unnamed Pakistan official was quoted as saying. Some reports suggested the name was mispelt.But the damage has been done. US analysts believe the Pakistani move is a shot across the US bow, since Washington had recently asked Islamabad for the names of all the operatives of the ISI's "S" division, which is said to handle ties with terrorist organization, and which the Obama administration , at the very least, believes may have been aware of bin Laden's hiding in Abbottabad . Taken together with the Pakistani security establishment’s persistent demand that Washington withdraw CIA personnel inside Pakistan, despite their stellar role in tracking down Osama bin Laden , the episode signals the end of the decades long fraternal dalliance between the two spy agencies that had its best moments during the Soviet presence in Afghanistan.In those halcyon days, the CIA worked hand-in-glove with ISI (and the ISI, the joke went, worked hand-in-pocket with CIA), as the United States funneled billions of dollars to Pakistan in an effort to oust Soviet troops from Afghanistan. US lawmakers were conducted to the front-lines by the ISI where they posed for pictures with the Afghan mujaheddin - photos which adorned their Capitol Hill offices just before 9/11.The suspicion in intelligence circles for the latest leak is focused on a senior Pakistani military official, Maj.Gen Athar Abbas, who is in charge of media relations in Islamabad. The alleged name of the CIA station chief was first broadcast on ARY television channel in which the military official's brother, Mazhar Abbas, is a news director. It was subsequently picked up by the right-wing newspaper, Nation, which is widely seen as a mouthpiece of the Pakistani security establishment.The same newspaper also printed the name of the previous CIA station chief Jonathan Banks, necessitating his hurried withdrawal from Islamabad. On other occasions, the newspaper has also published the coordinates of US officials and personnel in Pakistan, which Washington sees as endangering their security at a highly volatile time in a country where anti-American sentiments are rampant.According to intelligence sources, the breakdown in ties began after Pakistan's army chief Pervez Ashfaq Kiyani, began a review of the civilian government's policy of acceding to US demand to station a large number of American security experts in Pakistan in the hunt for high-value al-Qaida targets. The US is said to have used the opening to also track other terrorists groups such as Lashkar-e-Taiba, which were fostered by the ISI, a development that led to the flashpoint involving CIA contractor Raymond Davis.The Pakistani security establishment is blaming President Zardari and his Washington mandarin Hussain Haqqani for giving visas to some 7000 US personnel. Haqqani has rejected the charges. "7000 figure is incorrect & official records prove hype on subject is totally fabricated. All procedures followed," Haqqani tweeted on Sunday amid growing tensions within the Pakistani government.
