About 500 people protested Sunday in northwestern Pakistan, demanding the government account for the abduction and slaying of a journalist. His family believes he was taken by state intelligence agents. Hayatullah Khan's body was found on Friday, handcuffed and shot in the back, near Mir Ali in the North Waziristan tribal region where he was abducted on December 5. No one has claimed responsibility for abducting or killing Khan, but his relatives claim he was taken by the Inter-Services Intelligence or ISI, Pakistan's prime military-run spy agency. In January, a Pakistani government official said Khan may have been abducted by Islamic militants.
