“During an unannounced trip to Pakistan’s capital [Islamabad] on Friday [June 10, 2011], [CIA Director] Mr. [Leon] Panetta met with the leader of the Pakistani intelligence service, Lt. Gen. Ahmed Shuja Pasha, and showed him satellite photographs and other evidence of what the C.I.A. believes to be two facilities for the manufacture of bombs used by militants based in Pakistan against American forces in Afghanistan, the official said. The bomb facilities were in the northwestern districts of North and South Waziristan, both havens for militants. The official said Mr. Panetta was compelled to confront General Pasha after the C.I.A. alerted the Pakistanis about the existence of the bomb-making facilities several weeks ago and asked them to raid the locations. But when the Pakistani Army showed up, the militants were gone, making the C.I.A. suspicious that the militants had warning from someone on the Pakistani side. ‘The targets seem to have been tipped off,’ the American official said, adding, ‘There are indications that some senior Pakistani officials aren’t happy about it, and neither are we, of course.’ ”
