ISLAMABAD: CIA Director Leon Panetta and senior Pakistani officials planned to focus on the size and scope of US intelligence activities in Pakistan during a second day of talks Saturday, as both countries work to repair ties fractured by the American raid that killed Osama Bin Laden, a Pakistani official said. The operation that killed Bin Laden plunged an already strained relationship between the CIA and Pakistan's main intelligence agency, the ISI, to new lows and threatened cooperation that is key to the US fight against Al-Qaeda and Taliban militants battling foreign troops in Afghanistan. The US also needs Pakistan's help to help promote and guide negotiations with the Taliban that can help end the decade-long Afghan war. Pakistan and Afghanistan inaugurated a joint peace commission Saturday during a visit by Afghan President Hamid Karzai.
