US officials have voiced concern about Russia’s increasing military presence in Syria, saying it appears to be aimed at strengthening the government of Assad, a longtime Russian ally, rather than seeking a transition to a new political leadership.
Russian Federation has positioned about a half dozen tanks at an airfield at the centre of a military build-up in Syria, according to two United States officials.
Washington expressed concern over the Russian military build-up in Syria and put pressure on countries nearby to deny their air space to Russian flights to the country.
