In a parallel development, Syrian fighter jets launched heavy airstrikes on militants' concentration centers in various parts of Damascus, Dara'a, Deir ez-Zor, Hama, Aleppo and Idlib.
The northeastern and northern parts of Aleppo province are still scenes of fierce clashes between the Syrian Army and the militant groups as the government forces continue their offensive in the north in a bid to seal the border with Turkey.
"The Army troops have now engaged in heavy fighting with the terrorists near Manbij in the northeastern territories of Aleppo province, which claimed the lives of many militants," the Army said in a statement.
The Syrian Armed Forces and allied popular units have also launched a series of attacks on the bases and gathering centers of Daesh and al-Nusra Front in eastern and southeastern Aleppo on Saturday, killing and wounding many terrorists, Fars News wrote.
