The Syrian and Russian air forces continued their aerial onslaught against the Islamic State of Iraq and Al-Sham (ISIS) on Sunday, striking several of the terrorist group’s installations around eastern Syria.

The aforementioned air forces traded turns striking ISIS in the east Homs countryside, where the Syrian Arab Army’s “Tiger Forces” are currently advancing around northern Palmyra (Tadmur).

According to a trusted military source, the Russian Air Force destroyed one of ISIS’ hideouts in the Bardeh Mountains that are located between the ancient cities of Palmyra and Quraytayn in southeastern Homs.

In addition to the airstrikes in east Homs, the Syrian and Russian air forces targeted several ISIS sites in the Deir Ezzor, Al-Raqqa, Al-Sweida, and east Damascus countrysides, delivering a lethal blow to the terrorist group’s positions.

Recently, the airstrikes against the Islamic State militants have become more frequent; especially after the aforementioned terrorist group increased their activities around the vast Syrian Desert.
