According to the Syrian Army spokesman, the military forces have carried out successful operations in Daraa, Homs, Aleppo, Lattakia, Deir ez-Zor, Hama and Damascus over the past 48 hours.
In Aleppo, a joint operation by the army and the voluntary forces led to the liberation of tens of villages, SANA quoted the spokesman as saying.
Syria has been entangled in civil war since March 2011. The Islamic State in Iraq and the Levant (ISIL) Takfiri terrorist group controls parts of the Arab country, mostly in the east.
Meanwhile, Russia’s aerial support for the Syrian forces has given fresh impetus to the fight against the foreign-backed terrorists.
Since late September, Russia has been carrying out bombings against the ISIL terrorists in Syria, after Russia's parliament granted President Putin authorization to deploy the country's air force abroad.
In the past four and half years, more than 240,000 people have died in Syria -overwhelmingly civilians- and around 4 million Syrian people are now refugees in other countries. Around 8 million others have been displaced internally.
