A military source in Aleppo told Al-Masdar News on Tuesday that at least 7 batteries belonging to the S-300 anti-aircraft missile system were redeployed to the city of Al-Safirah in southern Aleppo.
Al-Safirah is the primary location of the Hezbollah and Iranian forces in southern Aleppo; it is also the site of one of the Syrian Army's largest bases in the province.
No reason was given for this recent move by the Russian military; however, on Tuesday, their navy began launching cruise missiles towards the jihadist defenses in the Aleppo Governorate.
