The army has recovered the office of the Local Administration Ministry in Al-Hasaba, Sana'a, as fierce confrontations continued between the forces and tribal fighters loyal to Sadeq Al-Ahmer, the sheikh of Hashid, the News Yemen reported on Wednesday.
Al-Ahmer's supporters took over the office and other public offices last week and at the end of the week a truce ended the deadly clashes and they returned some offices.
Houthi rebels fought for Al-Ahmer and the bodies of some of them were found inside the office, the website reported.
This week, the shortly-lived truce collapsed, with the battles resuming in the district and nearby areas and the tribal fighters retaking over more offices.
Meantime, antiterrorism and central security forces with support from pro-regime tribal fighters are fighting Al-Ahmer's loyalists as the government said it is determined to remove the tribal saboteurs.
Also, sporadic exchanges of gunfire were heard near the square of change outside Sana'a University on Wednesday, where tens of thousands of people have been conducting a sit-in to call for the departure of the regime.
Eyewitnesses said forces in plainclothes were firing inside populous areas near the square to terrify the people, but there were not casualties.
Huge explosions have been heard in the capital over the last two days as reports said almost 40 people were killed in the clashes between the army and Al-Ahmer's supporters.
