Eighteen people were killed in clashes between two tribes in Amran governorate, northern Yemen, in the two days past.
Local sources in Amran said that the clashes were renewed lately between Harf Sufian and Al-Osaimat tribes after the failure of a number of local mediation efforts to put an end to the clashes.
Over 74 people, including women and children, have been killed in the conflict which remains ongoing using various weapons.
The conflict between Harf Sufian and Al-Osaimat tribes has erupted since November 2008, according to local sheikhs.
The tribes belong to powerful rival tribal coalitions, the Bakil and the Hashid.
The conflict has its roots in the early 20th century with disagreements over land known as al-Sawad, bordering al-Osaimat and Harf Sufian areas.
