US gov't analyzes Bin Laden tape to determine date

The United States government was trying on Friday to pinpoint when Osama bin Laden recorded his most recent tape that warned about planned attacks on the US. Intelligence officials said analysts were scrutinizing the audio tape for any clues that might be a signal for the terror network's members or followers. A counterterror official said analysts believe the tape appears to have been recorded since December, although it isn't clear how recently. The audio recording was the first public statement by bin Laden since December 2004.
