On Tuesday, Syrian troops managed to capture two strategic villages: Doweir al-Zaytun and Tell JaLibin near the town of Paschkoa in Aleppo Province's northern area, with other army units winning back a key mountain in a region of Latakia that borders Turkey to the north.
"The main objective of this phase is to seal the northeastern corner of Lattakia province and build a frontline at the strategic city of Jisr al-Shughour," the sources were quoted by the Iranian news agency FARS as saying.
In Aleppo, the army's new advance came after Syrian forces cut two main supply lines of Daesh (ISIL/ISIS) terrorists in the province's north, according to the sources.
"The Masqan-Aleppo and Haras-Al-Bab roads, used by the ISIL terrorists as two main supplying routes, were cut in the attacks of the Syrian fighter jets and the army's artillery units," army sources said.
Also on Tuesday, the Syrian Army continued its offensive against militants in other key provinces across Syria, including Damascus, Homs, Deir ez-Zor and Quneitra, where dozens of terrorists were killed and many more wounded.
Russia's ongoing air campaign in Syria was launched on September 30, when more than fifty Russian warplanes, including Su-24M, Su-25 and Su-34 jets, commenced precision airstrikes on Daesh and Al-Nusra Front targets in Syria at the behest of Syrian President Bashar Assad.
In addition, the Russian Defense Ministry confirmed earlier this month that advanced, super-maneuverable Su-35S multirole fighters had begun their combat mission in Syria.
