WASHINGTON - Buoyed by Osama bin Ladens elimination, the United States is pushing Pakistan to identify some of its top intelligence operatives to determine whether any of them had contact with the slain Al-Qaeda chief, a leading American newspaper reported Saturday, The demand came in the wake of Pakistans failure to locate the hideout in Abbottabad, where the Qaeda leader was killed by US forces in a raid early Monday morning, the New York Times said, citing Pakistani officials. There is, the paper said, growing suspicion among United States intelligence and diplomatic officials that someone in Pakistans secret intelligence agency knew of bin Ladens location, and helped shield him. In particular, US officials have demanded information on the ISI, which has worked closely with militants since the days of the fight against the Soviet army in Afghanistan, the report said. Its hard to believe that Kayani and Pasha actually knew that bin Laden was there, a senior administration official said, referring to Pakistans army chief, General Ashfaq Parvez Kayani, and the ISI director-general, Lieutenant General Ahmad Shuja Pasha. But there are degrees of knowing, and it wouldnt surprise me if we find out that someone close to Pasha knew. Pakistani investigators involved in piecing together bin Ladens life during the past nine years said this week that he had been living in Pakistans urban centers longer than previously believed, the paper said Two Pakistani officials say that bin Ladens Yemeni wife, one of three wives now in Pakistani custody, told investigators that before moving in 2005 to the mansion in Abbottabad where he was eventually killed, bin Laden had lived with his family for nearly two and a half years in a small village, Chak Shah Mohammad, a little more than a mile southeast of Haripur, the report said. One of the officials said this means that bin Laden left Pakistans rugged tribal region sometime in 2003 and had been living in northern urban regions since then, the report noted. TheNation Monitoring adds: The US has asked Pakistan to show concrete actions to prove its commitment in the war against terrorism, even as it has sought an explanation from Islamabad on its ignorance about slain Osama bin Ladens hideout, reports The Economic Times. The statement in this regard came from the State Department amidst increasing questions being raised by lawmakers and think tanks on Pakistans commitment to fight against terrorism. Were going to look for concrete actions and concrete signs from the Pakistanis that theyre also committed to this, State Department spokesman Mark Toner told reporters here. At the same time, Toner said it is also important that US-Pak counterterrorism cooperation thats been going on since 9/11 has borne fruit and has led to some successes. It has put increased pressure on Qaeda and other terrorist groups operating within Pakistan. Terrorism is an existential threat for Pakistan, he said, adding thousands of Pakistanis have been killed both by Qaeda and other terrorist groups. So we believe its important that this kind of cooperation continue, he added. Toner said the US has asked a number of questions to Pakistan with regard to the hideout of Osama bin Laden in an affluent suburb of Islamabad. Certainly, weve raised these issues with them. The Pakistanis have said they have the same concerns, and theyre looking into it. Its hard for me to say. These kinds of investigations can take some time, he said. The US is looking for the Pakistanis to address what the Administration believes are legitimate concerns raised by it and the Congress. They recognise that well look to them to provide answers to those questions, he said.
