NEW YORK - The Obama administration is piling up pressure on Pakistan to provide the United States with broader information on airline passengers, including their recent travel histories and how they paid for their tickets, in an attempt to track terrorist travel patterns, The New York Times reported on Monday. Citing unnamed administration official, the newspaper said Pakistan was resisting the politically unpopular demand, but the US was pressing for information on Pakistanis who fly not only to the United States but also to other countries. The information thus collected would be fed into databases that can detect patterns used by terrorists, their financiers, logisticians and others who support them, The Times said in a front-page report. The report said that Pakistan had for several years rebuffed the request but the issue is now on a short list of sticking points between the two countries that have intensified since the failed Times Square car bombing attempt. Pakistan, like other countries, currently already provides the names of airline passengers travelling to the United States. But providing more detailed information to US, Pakistan said, would be an invasion of its citizens privacy, the report said. Apart from this issue, the short list of outstanding problems between the two countries includes some classified counterterrorism programmes, a long-running dispute over granting visas to American govt workers and contractors in Pakistan, and enhanced intelligence sharing. The United States, according to the newspaper, currently has a range of confidential agreements with countries governing how much information each will share about its citizens travelling on commercial airliners. Many countries share only information about passengers travelling to the US, while others, including several in the Caribbean, have agreed to share more information about other countries that their residents visit. President Barack Obama has given his top aides a deadline of the next few weeks to resolve the issues with Pakistan, the administration officials said. That pressure to deliver results has prompted senior officials like General James Jones, National Security Adviser, and Leon Panetta, Director of the Central Intelligence Agency, to warn senior Pakistani leaders of the risks to the countrys relationship with the US if a deadly terrorist attack originated in their country, the officials added. According to the report, some American aides have told Pakistani officials that the US might be forced to increase airstrikes in Pakistan in the event of such an attack, but senior US military officials said there was no special planning underway for such action. Pakistans Ambassador to the United States, Hussain Haqqani, reacted cautiously in a text message to the Times, which sought his comments. Terrorists are enemies of both Pakistan and the US, who need to discuss how to enhance cooperation and that is what we are doing, he said, adding, Pressuring an ally is not the way forward, and both sides understand that. In their visit to Islamabad two weeks ago, General Jones and Panetta presented Pakistans president, Asif Ali Zardari, and other top civilian and military officials with a description of links between the Pakistani Taliban and Faisal Shahzad, the suspect in the Times Square case, an administration official said. General Jones and Panetta thanked the Pakistanis for their cooperation in the investigation, but they also prodded their hosts to take tougher steps against the Taliban and other groups, and to resolve several issues that Pakistan has delayed, the report said. The United States is proposing to open a new consulate in Quetta, where the CIA would most likely have a sizable presence, it said. The White House also wants Pakistan to end a months-long dispute over refusing to grant visas to American govt workers and contractors in the country. In the wake of the failed Times Square terrorist attack and its direct links to extremist groups based in Pakistan, the President instructed General Jones and Director Panetta to go deliver a clear message to Pakistani authorities of the need to step up our counterterrorism cooperation to prevent an attack on the homeland and to address a common terrorist threat, Michael Hammer, a National Security Council spokesman, was quoted as saying. The airline passenger issue, which General Jones and Panetta also raised in their meetings, is particularly contentious but has remained largely out of public view, The Times said. We are offering to assist the Pakistanis with their border control challenges, including providing them technology and expertise that will allow them to better manage and monitor travel into and out of Pakistan for security purposes, said a senior administration official. Analysts at the National Targeting Centre in northern Virginia, an arm of United States Customs and Border Protection, could, for example, examine the travel patterns of Pakistanis with known links to militant groups who fly to Persian Gulf countries where donors to Al Qaeda and the Taliban live, the report said. But it would be explosive with Pakistani public opinion for the government to be seen as cooperating with the United States on the identities of Pakistani passengers. A recent poll by a Western embassy in Islamabad showed that only 4 percent of the respondents had a favourable view of the United States, so sharing individual names with the American government would be immensely unpopular. We know this is sensitive for the Pakistan government, and were trying to strike the right balance, a senior administration official was quoted as saying. The renewed urgency in the negotiations comes against the backdrop of evidence that both Shahzad and Najibullah Zazi, an Afghan nations who was airport shuttle bus driver arrested last fall as the main suspect in a failed plot to bomb three New York City subway lines, received training in Pakistans tribal areas.
