The Syrian and Russian air forces carried out a powerful series of airstrikes on Thursday evening that targeted the Islamic State of Iraq and Al-Sham’s (ISIS) defensive positions in the Maskanah Plains of east Aleppo and west Al-Raqqa.

According to a military source in Latakia, the Syrian and Russian air forces killed an estimated 40 ISIS fighters in the Maskanah Plains, while also destroying number of hideouts used by the terrorist group to attack the nearby Khanasser Plains of east Aleppo.

With the recent arrival of reinforcements to the east Homs front, the Syrian and Russian air forces have intensified their airstrikes over east Aleppo and west Al-Raqqa in order to weaken the ISIS’ supply route to the Palmyra countryside.

In addition to their airstrikes over the Maskanah Plains, the Russian Air Force targeted the ISIS strongholds of Deir Hafer and Al-Bab, killing a large number of terrorist combatants in the process.
