Two rival Libyan tribes, the Tuareg and Toubou, have signed a ceasefire deal in Doha to end months of fighting, Qatar state media has reported. The deal, signed on Monday, not only seeks to end 14 months of fighting in the southwestern Libyan city of Ubari but also help thousands of displaced people return to their homes. The agreement was signed by heads of delegations of both tribes in the presence of a Qatari assistant foreign minister, Sheikh Mohammed bin Abdulrahman bin Jassim Al-Thani, reported the Qatar News Agency (QNA).
