At least 30 people have been killed in fresh clashes between tribes loyal to the opposition and Houthi groups in Yemen's province of Jawf, newsyemen.net reported on Monday.
The figure was the result of three days of fighting that resumed on Friday, the website quoted sheikh Hassan Abu Hadra as saying.
The revolutionaries who are seeking the ouster of the regime took control of the province triggering clashes with the Houthi followers who tried to take over it themselves four months ago.
An opposition-led mediation to contain the conflict between the Houthi followers and opposition fans in the province failed to put an end to the situation there, as the Houthi followers try to take over military posts.
Separately, the battles between the army and tribes in Arhab district on the outskirts of the capital Sana'a resumed earlier Monday with the republican guard shelling some villages heavily. On Sunday, some people were killed and injured and homes destroyed in the continuous battles.
The republican guard posts have heavily shelled villages and the tribes fought back targeting some camps, according to locals.
Furthermore, the republican guard is shelling Taiz province killing and displacing people as well as destroying homes.
The Joint Meeting Parties, the opposition coalition, held the governor and the local government responsible for the army attacks in Taiz.
