ISLAMABAD, Jan 16: The US-led coalition, has found no clue of the prime suspect of Sept 11 attacks, Osama bin Laden, or Taliban leader Mulla Mohammad Omar.

“We simply do not know about Mulla Omar or Osama bin Laden,” coalition spokesman Kenton Keith said here on Wednesday, the last day of his stint in Pakistan.

Keith did not rule out the possibility that Osama might have escaped through sea route. “It is equally conceivable that Osama is present in the same area where coalition forces have been carrying out search,” he added.

“On land, on sea and in the air, Osama and Omar are being sought and that process would continue,” he added.
