Abdullah Aitha, who commands rebels fighting in the southeastern Kufra region of Libya, has said NATO destroyed a caravan of hundreds of camels carrying heavy caliber machine guns, mortars and ammunition.
He said the air strike came Friday evening in a desert 100 kilometres (62 miles) from the Chad border while the caravan was headed for the city of Sebha, 400 miles (650 kilometres) south of the capital Tripoli.
Sebha is a key Gaddafi stronghold deep in the country's southwestern deserts where much of the Libyan leader's loyal troops hail from.
"The camels are totally burned and the weapons are all destroyed," Aitha told the Associated Press.
NATO could not be immediately reached for comment.
