The Pakistani government must explain how Osama bin Laden was able to hide in Abbottabad for years and reveal who in Pakistan helped him, Pakistan's former Ambassador to Washington Husain Haqqani said Wednesday. "It's Pakistan's responsibility to the world to say who did it," Haqqani told an audience at the Center for the National Interest, formerly known as the Nixon Center.  "It doesn't have to be the government, it doesn't have to be the military, but whoever it is, we have to come clean on that, because that is the only way we will assure the rest of the world that Pakistan's government and Pakistan's state has its hands clean on this whole thing." Haqqani said that he has no information on how the late al Qaeda leader lived with a large number of family for five years in a military garrison town, but that there were clearly sympathizers in Pakistan that supported bin Laden and the government has failed to issue any report on who they were. "There's no report on bin Laden yet. No one is saying it was the government ... but somebody helped him. Somebody bought the place for him, somebody paid for the electricity bills, somebody helped bring food there, and at least that should be identified and it hasn't been," he said. "Somebody knew. I mean, nobody lives anywhere without anybody knowing. Even Friday knew where Robinson Crusoe was. Somebody in Pakistan knew. Who that somebody is, it's Pakistan's responsibility to identify."
