DAMASCUS (Sputnik) — According to the source, the attack was carried out by militants of al-Nusra Front and other extremist groups.
"The terrorists suffered losses, including influential field commanders," the source added.
The source noted that the terrorists managed to take control over just one village in the province, but the Syrian army was trying to liberate it.
The Russia-US brokered ceasefire in Syria came into force on February 27. Al-Nusra Front and Daesh terrorist groups, which are outlawed in Russia, are not part of the ceasefire deal.
