"Colonel Fiqhi is most probably responsible for the crimes took place in Zawiyah town," Khaled al-Warfali from the opposition told al-Arabiya in a phone call.
Earlier, NATO raided Bir al-Ghanam and al-Egila areas southwest of Tripoli.
The attacks led to civilian casualties, the Libyan news agency said without giving further details.
NATO planes on Sunday morning bombed barracks and radar installations in the Libyan town of Boukamache, some 17 km from the Tunisian border, the official TAP press agency reported.
The bombings which could be heard at the Ras El Jedir border crossing point, provoked panic among a number of Tunisians on their way back to Tunisia, TAP said, adding following the bombings, a large number of Libyan refugees fled the region and crossed into Tunisia.
Libyan state TV broadcast a recorded audio message from leader Muammar Gaddafi Friday evening in which he says he is still alive after claims earlier in the day he may have been hurt in NATO airstrikes.
The broadcast also came after the Libyan government accused NATO bombing of killing more people in the oil town of Brega. (*)
