ROUGH CUT ONLY - NO REPORTER NARRATION
  Libyan forces celebrate the capture of Muammar Gaddafi's hometown of Sirte.
  There are conflicting and unconfirmed reports that the deposed leader has been captured or killed.
  A National Transitional Council official told Reuters Gaddafi was killed in a firefight.
  The capture of Sirte means the NTC can now begin the task of forging a new democratic system, which it had said it would get underway once the city built as a showpiece for Gaddafi's rule had fallen.
