Khaled Kaim also slammed the international community for allowing rebel forces to operate aircraft despite the existence of a no-fly zone over the country following U.N. Security Council resolution 1973.
The report could not be confirmed with the rebels, but journalists in the area did describe seeing at least one helicopter apparently fighting for the rebels in the area Saturday, though it lacked the distinctive double rotor design of Chinook and appeared to be a Russian built model.
Most aircraft used by the Libyans, whether government or rebel forces, are Russian made, however, but the Directory of World Air Forces from 2008 says Libya had 20 Chinooks, which are used primarily for transport and heavy lifting, in service.
While the Libyan government forces still possess most of the military aircraft in the country, a few were taken by the rebels when some air force units defected in the east of the country following popular uprisings against Moammar Gadhafi's four decades of rule.
NATO, which enforces the no-fly zone said it has been has been applying it to both sides and on Saturday intercepted a rebel MiG-23 fighter jet and forced it back to the airport.
Rebels have criticized the NATO for not giving them sufficient battlefield support as government forces continue to push into the east.
On Saturday, fighting continued over the city, with fleeing civilians reporting both sides shelling each other.
At least 11 people died in Saturday's fighting, reported Ajdabiya hospital supervisor Mohammed Idris, with two more rebels killed Sunday.
Recapturing the Ajdabiya would give the Libyan military a staging ground to attack the rebels' main stronghold, Benghazi, about 100 miles (160 kilometers) farther east along the coastal highway. Gadhafi's forces were approaching Benghazi when they were driven back by the international air campaign launched last month to protect civilians and ground Gadhafi's aircraft.
