The head of the Antiquities Authority in Tripoli, Mohamed Faraj, said that negotiations are underway with Spanish authorities to restore Libyan artifacts dating back to the Greek era.

Faraj told Xinhua on Thursday that negotiations with the Spanish authorities reached advanced stages after the identification of six pieces stolen from the site of the archeological city of Shahhat in the east Libya.

Faraj pointed out that these artifacts have unique features and signs that are only found in Libya, adding that the number of pieces expected to be recovered from Spain could reach up to 25 ones after it was first thought to be 11.
