Russian combat aircraft have conducted 164 sorties and hit 556 terrorist targets in Syria over the past three days, the Russia’s General Staff said Monday.

“In three days, starting December 25, [Russian warplanes] conducted 164 sorties, hitting 556 terrorist targets in the provinces of Aleppo, Idlib, Latakia, Hama, Homs, Damascus, Deir ez-Zor and Raqqa,” chief of the Main Operational Directorate of the General Staff of the Russian Armed Forces Sergei Rudskoy told reporters.

Russian jets have intensified airstrikes to aid the anti-terrorist offensive of the Syrian army and patriotic opposition forces, he stated.

According to Rudskoy, Russia’s air campaign has helped the Syrian army to establish control over part of the country’s border with Turkey.
