Anti-Gaddafi forces advance toward the town where some believe the Libyan leader is hiding.Despite the ruling interim council's earlier promise of a week-long grace period for negotiations, the forces said they would attack the town of Bani Walid Sunday.Moftah Mohammed, a rebel from Bani Walid said, "We are now on the border of Bani Walid, between Tarhouna and Bani Walid and we are coordinating with rebels from Misrata -- we are hoping to enter the town today or tomorrow, God willing."A National Transitional Council official said they know roughly where Muammar Gaddafi is but would not give details.NTC forces also guarded a grape farm south of Tripoli after residents uncovered a cache of landmines.They asserted they did not need international help dealing with the more than 6000 explosives after the EU expressed concern about youths getting hold of the weapons.Siaf Amari, Yafran anti-Gaddafi soldier said, "Slowly but surely, one of our main objectives is to bring stability back to Tripoli. One of our main objectives is if the weapons are in the wrong hands we are going to take them away. We are qualified to do that. Very qualified to do that."However, other weapons stores lie unguarded as forces near the capital have not deployed sufficient manpower to remove munitions close to residential areas.
