Explosions Heard near Damascus at Iranian Base - LIVE BREAKING NEWS COVERAGE
Russia is still extensively using a large airbase in central Syria to launch sorties against positions for the rebel groups across the country, satellite images reveal.
The images, released online, clearly show four SU-25 jets, as well as a squadron of helicopters including three Ka-52 attack helicopters.
The highly-operational T-4 airbase hosts Russian as well as Iranian forces which help the Syrian Army fights the terror groups across the war-torn country.
Last month, the Iran-run section of the airbase has come under missile attack by Israeli warplanes, which killed and wounded a dozen of Syria soldiers and Iranian military advisors.
The attack, according to Israeli sources, targeted a building operated by Iranian military experts who repeatedly flew drones into the Israeli territories.
