Libya's opposition is offering a $1.67 million reward for the capture of Moammar Gadhafi.

Transitional National Council leader Mustafa Abdel Jalil said Wednesday his opposition group supports a decision by local businessmen to provide the reward, in an attempt to speed up Mr. Gadhafi's capture.

The former leader's whereabouts are unknown, but U.S. officials say they believe he still is in Libya.

Earlier Wednesday, fighting broke out again at the Bab al-Aziziya compound in Tripoli, a day after rebel fighters overran the former Gadhafi headquarters.

A leader in the anti-Gadhafi forces, Anis Elsharif, told VOA that opposition fighters are continuing to battle government loyalists in some pockets of Tripoli.

Clashes also continue in Zuara, a town west of Tripoli.

A pro-government television channel has quoted Mr. Gadhafi as saying he retreated from his Tripoli compound in a “tactical move,” following dozens of NATO airstrikes. Al-Rai TV reported Wednesday that Mr. Gadhafi addressed Libyans on a local radio station, saying he vowed martyrdom or victory in his fight against what he called NATO aggression.

In a separate development, journalists who had been detained by pro-Gadhafi forces were freed on Wednesday. Government forces had held approximately 35 journalists at a Tripoli hotel for four days.

TNC leader Jalil said Tuesday that days of fighting in Tripoli had left more than 400 people dead and 2,000 wounded. He did not specify whether he was talking about both sides in the conflict.
