The UN on Thursday called on all parties concerned in Hajoor tribal areas, in the Yemeni northwestern governorate of Hajjah, to practice self-restraint and refrain from any acts furthering escalation, as the tribes declared formation of alliance to fight Houthis.
UN spokesman said their humanitarian coworkers "feel concerned" at military activities in Hajoor and ramifications resulted from continuing violence on civilians' life.
The UN calls on parties to exercise self-restraint and refrain from any acts leading to more escalation, particularly with civilians continuing to pay heavy price, Stephane Dujarric told reporters.
Houthis have started a widespread offensive since last January on Hajoor tribal areas in Cashir District, amid strong resistance by tribesmen who had repelled rebel control, with Saudi-led coalition warplanes backing the tribes by periodic strikes on Houthi reinforcements and equipment.
On Thursday, Houthi group stated that its forces had fully secured al-Abeesah and neighboring areas in Cashir, "from ravaging outlaws connected to aggression."
Meanwhile, Hajoor tribes declared the formation of tribal alliance containing a number of sheikhs to fight Houthis.
Four of Hajoor tribal leaders have covenanted to fight Houthis until victory or death, the Saudi al-Arabiya TV quoted local sources as saying on Friday, naming the sheiks who "obtained tribesmen's consensus on their selection as tribal and field leaders."
Sources claimed that Hajoor tribesmen were still positioning themselves at sites they had recently held in the southern front.
The Yemeni official government's information minister warned of "genocide crimes and terrifying atrocities committed by Houthi group against civilians in Cashir."
In a set of tweets, seen by Debriefer, Minister Mo'ammar al-Eryani said Houthi forces intensified attacks on the district's villages, targeting citizens' houses, schools and mosques with ballistic missiles and different weapons.
According to field information, hundreds of civilians have been killed or injured by Houthi shelling, Eryani added. The "shocking silence of the World and human rights organizations at such carnages .. gives negative indication and green light for Houthi militias to kill civilians in Hajoor and other rebel-held areas."
Legitimate government forces control parts of Midi and Haradh districts, while other territories of the 31-district governorate of Hajjah are under Houthi-control.
Yemen has been racked by an armed conflict that broke out after the Iranian-backed Houthis had ousted the internationally recognized government late in 2014, leaving tens of thousands killed, hundreds of thousands injured, and 3 million displaced.
