ABBOTTABAD, Pakistan (AP) — Pakistan criticized the American raid that killed Osama bin Laden as an "unauthorized unilateral action," laying bare the strains the raid has put on an already rocky alliance. A day after U.S. commandos killed the world's most wanted man after a 10-year manhunt, new details emerged Tuesday from Pakistan's powerful intelligence agency and neighbors of bin Laden that raised more questions about whether some elements within the security forces knew, and perhaps protected, the al-Qaida chief. Neighbors in the city of Abbottabad, a two-hour drive from the Pakistani capital, sensed something was odd about the house where bin Laden and members of his family lived, even though the terror chief and his family rarely ventured outside and most residents were not aware that foreigners were living there.
