WASHINGTON (AP) — The CIA’s targeted killing program in Pakistan, once the mainstay of President Barack Obama’s counterterrorism effort, is winding down.

Because of stricter rules, diplomatic sensitivities and the changing nature of the al-Qaida threat, there hasn’t been a U.S. drone strike in Pakistan’s tribal areas since Christmas. And American officials say opportunities for drone attacks will dwindle further as the CIA and the military draw down in neighboring Afghanistan, reducing their intelligence-gathering footprint.
