The ISIL left behind tens of the dead and wounded members and fled its strongholds near al-Sha'er and al-Maher oilfields under the heavy offensives of the Syrian government forces.
The ISIS military hardware also sustained major damage in the attacks.
The Syrian fighter jets, for their parts, hit heavily the Daesh concentration centers near al-Maher, al-Sha'er, Eastern side of Palmyra (Tadmur), the village of Um al-Tababir and al-Masak valley, which ended in the killing or injuring of dozens of the terrorists.
Earlier reports said that the Syrian Army aircraft, in a fresh round of anti-terrorism combat sorties, targeted the ISIS strongholds near two energy-rich regions in the Central province of Homs, inflicting a heavy death toll on the terrorists.
The ISIL concentration centers in the Eastern side of Jazal oilfield, the Northern and Western sides of al-Maher gas field and the Western side of al-Maher pumping station were heavily bombed by the Syrian warplanes.
At least 12 ISIS terrorists were killed and several more were wounded in the attacks, FNA reported.
