Russia positioning tanks at Syria airfield: U.S. officials

WASHINGTON (Reuters) – Russia has positioned about a half dozen tanks at an airfield at the center of a military buildup in Syria, two U.S. officials said on Monday, adding that the intentions of Moscow’s latest deployment of heavy military equipment were unclear.

Moscow has come under increased international pressure in recent days to explain its moves in Syria, where the Kremlin has been supporting Syrian President Bashar al-Assad in a 4-1/2-year war.
