Ali Tarhouni,Libyas interim oil minister,said on Saturday they were closing in on bastions of support for Gaddafi. Offering Libyans some hope of an end to conflict and a more prosperous future,Tarhouni said during a news conference in Tripoli that he had been told by commanders that the pro-Gaddafi bastion of Bani Walid may have changed sides. A senior military source in the forces of the National Transitional Council had told Reuters earlier that NTC leaders were close to reaching an agreement with tribal leaders in Bani Walid on their imminent peaceful surrender. Tarhouni reaffirmed assurances by the former rebels that Gaddafis capture was near we know where he is, he said.
