ADEN, Yemen, May 22, 2018 (MENA) - Scores of Houthis were killed on Tuesday during clashes in Hajjah governorate in northern Yemen close to the borders with Saudi Arabia. This comes at a time when the Yemeni legitimate forces, supported by the Arab coalition under Saudi Arabia, are reportedly achieving a progress on the war fronts in Hajjah after three-day clashes with Houthis. Yemeni Ministry of Defence sources confirmed that the Yemeni Army succeeded to liberate new sites in Haradh and Al-Kassra areas in Hajjah, where the military operations resulted in deaths of dozens of Houthi terrorist elements, including two of its leaders.
