(CNN) -- The United States does not know where ousted Libyan leader Moammar Gadhafi is and does not believe the National Transitional Council has a lock on his whereabouts either, a senior U.S. official told CNN Thursday.

That information came after Anees al-Sharif, a spokesman for the new Tripoli Military Council, said anti-Gadhafi fighters had cornered the fallen Libyan leader and that he had no means of escape. Al-Sharif did not divulge a location.

U.S. Defense Secretary Leon Panetta said earlier this week that officials believe Gadhafi is on the run. "I don't have any information as to exactly where he's located," he said.

Two Libyan convoys passed through Niger this week, officials in that country said. Initial speculation was that Gadhafi was in one of those groups, but on Thursday a second senior U.S. official said the United States now has a list of officials from Libya who were in both convoys.

There were "no marquee names," or anyone who was named in U.N. Security Council resolutions, the second source said. The official would not say who was in the convoys but said Gadhafi's security chief was not among them, refuting reports that said he left in the convoy.

The Nigerien government is talking to the NTC about what the new Libyan leadership wants to do with those in the convoy but the NTC hasn't decided whether it's worth it to bring them back, the source said.

Libyans are leading the search for Gadhafi. The Central Intelligence Agency has agents in the area, and the United Kingdom, France, Jordan and Qater have special forces in the country as well, NATO and U.S. defense officials tell CNN. However, the mission of those agents is not necessarily focused on hunting for Gadhafi.
