According to the report, seven Russian T-90 tanks have been spotted at an airfield near Latakia.

Russian artillery units have also been deployed in the area, allegedly for protection of the Russian troops stationed there.

Pentagon did not confirm the agency’s report citing reasons of secrecy. However, some Pentagon officials say that Russia’s activities in the area indicate it is going to set up an air traffic control installation near Latakia.

Reuters earlier reported Russia sending 200 marines and antiaircraft system components to Syria.
