The images suggest four helicopters and 20 lorries were destroyed by fire inside the T-4 base, which is also known as Tiyas and is strategically located in central Syria between war-ravaged Palmyra and Homs.
"The T4 air base was severely damaged by an Islamic State artillery attack. In particular, four Russian Mi-24 attack helicopters appear to have been destroyed," Stratfor said on their website.
Russia has not officially commented on the incident.
