Moscow's intervention in the Syrian conflict will have the unintended consequence of drawing Russia into a quagmire which will give it an incentive to work for a political transition, U.S. Deputy Secretary of State Antony Blinken said on Saturday. "The quagmire will spread and deepen, drawing Russia further in. Russia will be seen as being in league with Assad, Hezbollah, Iran, alienating millions of Sunnis in Syria, the region and indeed in Russia itself," he said at a security conference in Manama. As part of Moscow's capaign against ISIS militant group, Russian jets are bombing rebels opposed to Sryian President Bashar Assad, who is also supported by Iran and Hezbollah.
