Satellite images of Russian build up in Syria
The attached tweets show clear images of Russian aircraft at Latakia's airport.  Apart from jets, tanks and helicopter gunships, the Russian are said to have deployed﻿ surface-to-air missile systems which is somewhat confusing given that ISIS is not known to have any aircraft.  Hence the US concern that Syria is being lined up to become a new Russian protectorate for the long-term.

International attention is turning back to the Syrian government as Russian involvement in the country grows increasingly more apparent. This week, more evidence emerged of the extent of this influence when satellite images showed Russian crafts parked in Syrian President Bashar al-Assad's strongholds.

Collected as part of a report by AllSourceAnalysis and the Institute for the Study of War, the images confirmed Russian military equipment at an airbase in the city of Latakia, the Syrian government's coastal stronghold. Battle tanks, helicopters and personnel carriers dotted the airbase in images captured on Sept. 18.

The analysis group captured another shot the following day, this time showing at least four Russian Su-27 fighter jets parked at the Latakia airbase. Introduced to Soviet forces in 1985, the jet was built to compete with US F-14 and F-15 fighter models. Today it's most closely comparable to the US-made F-15 Eagle.

Earlier this month, satellite images also identified ramped up contruction at the Al-Assad International Airsport in Latakia, potentially to prepare for Russian troops and equipment. Here's that image below, via Twitter.

The images follow confirmation from a senior US official on Friday of Russia's new influence in Syria. The official told the New York Times four Russian Su-27 fighter aircraft, four large Hip troop-transport helicopters and four Hind helicopter gunships had appeared in Latakia in recent days.
