Two citizens were wounded and major damage was inflicted on properties in militants' mortar attack on al-Bayrouni Hospital in Damascus, police said, adding the university of Aleppo was also targeted by the rebels. A Police source told the State News Agency that a mortar shell landed behind al-Bayrouni Hospital on Friday, wounding two citizens and causing damage on properties. Four other shells fell in Talet al-Amjad and the B4 areas and near Harasta suburb bridge, causing material damage to buildings and cars but no casualties. Terrorists have lately showered Harasta suburb with scores of shells, leaving tens of citizens dead or injured. Meanwhile, terrorists in the Northern countryside of Lattakia fired a rocket shell on the faculty of Mechanical and Electrical Engineering -Industrial Institution- at Tishreen University in the city. The conflict in Syria started in March 2011, when sporadic pro-reform protests turned into a massive insurgency following the intervention of western and regional states. The unrest, which took in terrorist groups from across Europe, the Middle-East and North Africa, has transpired as one of the bloodiest conflicts in recent history. As the foreign-backed insurgency in Syria continues without an end in sight, the US government has boosted its political and military support to Takfiri extremists. Washington has remained indifferent to warnings by Russia and other world powers about the consequences of arming militant groups.
