Pakistan Government May Have Been Involved In Saleem Shahzad's Killing

   The US military's top officer said Thursday Pakistan's government may have sanctioned the killing of journalist Saleem Shehzad, voicing grave concern over the attack.    Asked about media reports that Islamabad sanctioned or approved the killing of the reporter, Admiral Mike Mullen said: "I haven't seen anything that would disabuse that report."
   He said he was "concerned" about the incident and suggested other reporters had suffered a similar fate in the past. "His (death) isn't the first. For whatever reason, it has been used as a method historically."    While acknowledging that Pakistani officials have denied the government had any role in the death of Saleem Shahzad, Mullen said the episode raised worrying questions about the country's current course.
   "It's not a way to move ahead. It's a way to continue to quite frankly spiral in the wrong direction," said Mullen, who has held numerous meetings with Pakistani counterparts during his tenure as chairman of the US Joint Chiefs of Staff.
   Mullen said he could not confirm whether the ISI was behind the killing.
