The bodies were found on Thursday night in Al-Abyar, about 70 km (44 miles) east of Benghazi. The security sources gave no information about their possible identity.
Smaller numbers of bodies have been found in and around Benghazi on several occasions in recent months. The area is controlled by the Libyan National Army (LNA), a force headed by eastern-based commander Khalifa Haftar.
He declared victory in a campaign for Benghazi in July, though some fighting has continued in one district of the city.
