Three months after the forced medical escape of President Ali Abdullah Saleh, a political situation in Yemen threatens to escalate into open confrontation between Saleh loyalists and opponents. The elite Republican Guard army, commanded by Ahmed, the eldest son of Saleh, have reinforced their presence in Sanaa and deployed tanks on the hills overlooking the capital. Troops loyal to dissident General Ali Mohsen al-Ahmar, fewer and less well armed, have fortified their positions in areas they control in Sanaa, mainly around University Square, renamed Change Square by protesters, Alarabiya.net reported.
