A citizen was killed and others injured as the republican guard continued shelling some areas in south and north Yemen on Monday.
In Nihm district on the outskirts of Sana'a and where the army has been battling the tribes for more than a month, citizen Abdu Barakat was killed and others injured when the republican guard heavily targeted some villages.
In nearby districts including Arhab and Bani Matar, hundreds have fled over the past days amid strikes from the republican guard camps that destroyed homes and affected markets and farms.
Sporadic battles have been reported in these districts after reports said that tribesmen took over military camps and prevented republican guard forces from heading to the capital Sana'a to crack down on the protesters calling for the ouster of the regime.
In the southern city of Taiz, the republican guard forces have been shelling villages in the district of Sharab for weeks since a tribal elder vowed to defend the antigovernment protesters who retook the square of freedom in downtown Taiz.
The forces launched their fiercest attack at homes leaving many injured after several soldiers and civilians were killed and others injured in the past two days.
Also, Tens of families have fled northern parts of Taiz amid the confrontations, as civil society organizations described the military operations as crimes against humanity.
The developments come as the UN mission which arrived here to investigate human rights violations amid the month-long unrest is still doing its job.
So far, the mission has visited squares of change and freedom in some cities and met with some victims.
