Libyan rebels flank Gaddafi
The council's deputy defence minister said, however, that Libya's former rebels had no idea where Gaddafi was, and they were focussing on taking control of territory instead of tracking down the former leader.
Figures in Libya's new government have given a series of conflicting statements about Gaddafi's presumed whereabouts since the fall of the capital last month and many reports about his location have proven untrue.
Anis Sharif told the media that Gaddafi was still in Libya and had been tracked using advanced technology and human intelligence. Rebel forces have taken up positions on all sides of Gaddafi's presumed location, with none more than 40 miles (60 km) away, he said, without providing details.
"He can't get out," said Sharif, who added the former rebels are preparing to either detain him or kill him.
NATO said that it had made a number of airstrikes around Sirte on Tuesday, hitting six tanks, six armoured fighting vehicles and an ammunition storage facility. They also targeted the Gaddafi loyalist strongholds of Hun, Sabha and Waddan.
