On Thursday a car bomb exploded on the outskirts of Damascus near a Shiite mosque. The blast killed three people and injured dozens more, the Voice of Russia reported.
Despite their efforts security forces failed to prevent two more roadside bomb blasts in the same area.
In Aleppo demonstrators gathered in Marjah Square, the main square of the city, demanding the withdrawal of armed groups from the city and asking the Syrian Army to come to their aid.
In response armed insurgents opened fire on the unarmed street protestors.
Preliminary reports say there are dead and wounded. However no accurate information about the exact number of victims has been released.
