Insecurity has returned to the Capital Sana'a and other main cities as armed men blocked main roads and entrances linking between the capital and other cities.
Media sources said that road blockades renewed after the former president Ali Abdulah Saleh held a meeting with tribal leaders last week.
Efforts of some mediators to end blockades in an entrance of the capital failed to persuade armed men affiliated to Sheikh Sagheer Ben Azeez who is loyal to the Saleh to withdraw from the northern entrance of the capital.
The armed men impeded movements of individuals and commodities between the capital and the neighboring city of Amran.
Tribal sources affirmed that sheikhs sought to persuade Bin Azees to withdraw his followers from the entrance, pointing out that there are no signs of ending the blockade soon.
Armed manifestations remerged in Taiz and efforts of its new governor Shawki Anaam to settle down the tension in the city failed, particularly as the phenomenon of abducting military officers and political activists of the city increased.
Meanwhile, security of the port city of Aden deteriorated and that pushed the Defense Minister Mohammad Nasser Ahmed to hold a meeting with local authorities in Aden and gave an ultimatum to the armed men to withdraw.
Media sources said Ahmed accused some officials of Aden's local authority who are connected to the former regime of supporting armed men to block roads, raise chaos and spread drug among youth.
Governor of Aden Waheed Rasheed said that conflicts that Abyan are currently witnessing badly reflected on Aden's security, pointing out that most security officials and soldiers do not present to their jobs in city.
