Some serious accusations against Pakistan from U.S. officials in Friday’s Washington Post:

“Collaboration is growing between Taliban commanders in Afghanistan such as Haqqani, who has tribal roots in Paktika province, and Pakistanis such as Baitullah Mehsud, a commander in South Waziristan who is reorganizing the Taliban with help from agents in Pakistan’s intelligence service, according to U.S. military officials. Mehsud, the CIA has said, is responsible for the assassination of former Pakistani prime minister Benazir Bhutto in December.”
