Media reports indicated that many armed tribesmen have been deployed on Thursday afternoon in the northern part of the Yemeni capital of Sana'a.
Al-Ahali online newspaper reported citing eyewitnesses that tribal armed men were deployed in large numbers in Al-Jaraf and Marib streets as well as in Amran roundabout.
Their presence is contrary to the efforts exerted by the Military Committee—formed as per the GCC-initiated power transfer deal-- to remove the armed manifestations from the central cities, most particularly from Sana'a.
Last week, armed followers of a tribal sheik who is an ally of former President Ali Abdullah Saleh cut off Amran road which connects Sana'a with Amran province, the hometown of Sadeq al-Ahmar whose followers battled with Saleh's loyal forces last year in the capital's streets.
This escalation comes after the tribal chief's son was killed in clashes with rivaling tribesmen in the area.
For its part, the National Unity Government failed to remove the armed men presence from around the main entrance to Sana'a, al-Azraqeen.
The closure of the entrance linking Sana'a and Amran by the angry tribesmen led to the halt of the people's and goods' movements. It was widely perceived as the first of its kind tribal escalation since the new government has come to office late last year.
