Russian long-range bombers returned to action over Syria after a pause of just over two months in an attempt to drive back Islamic State forces besieging a government-held city in the east of the country. The Russian Ministry of Defence (MoD) announced on 25 January that Tupolov Tu-22M3 ('Backfire') bombers flew 18 sorties to engage Islamic State assets in the eastern province of Dayr al-Zawr (Deir ez-Zour) between 22 January and 24 January. While the MoD did not say where the sorties were launched from, it has been previously revealed that the Russian Aerospace Forces (VKO) deployed Tu-22M3 bombers to the Mozdok Air Base in North Ossetia to support the military intervention in Syria.
