The army units killed over 200 terrorists in fierce clashes in Quneitra province.
Meantime, the Syrian army took full control of the Meliha town in Eastern Ghouta in Damascus countryside.
Mleiha is located on a road leading to Damascus International Airport in Eastern Ghouta and it is considered the most important hideout of militants.
Control over Meliha can help the army restore security to the town of Jaramana in the vicinity of Meliha.
Government troops started their advances in Mleiha yesterday.
The so-called Syrian Observatory for Human Rights also reported the advance.
Like the rest of the Eastern Ghouta area, Mleiha has been undergoing fierce clashes for weeks.
"Its capture would be very important for the army to secure Jaramana," said Observatory director Rami Abdel Rahman, referring to a majority Druze and Christian suburb of Damascus near Mleiha.
Its fall from militants’ hands would also be key for the Syrian army's bid to take back the Eastern Ghouta area, a militant bastion.
Syria sank into war in March 2011 when 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.
