US Secretary of State Hillary Clinton has warned Russia of the grave consequences that would result from backing the Syrian regime of President Bashar al-Assad. \"The situation is spiraling towards civil war, and it\'s now time for everyone in the international community, including Russia and all Security Council members, to speak to Assad with a unified voice and insist that the violence stop, and come together with Kofi Annan to plan a political transition going forward,\" US Secretary of State Hillary Clinton has said at a press conference in Washington. \"It is something that we believe is in everyone\'s interests, most particularly the Syrian people. And Russia says it wants peace and stability restored. And it also claims to have vital interests in the region and relationships that it wants to continue to keep. They put all of that at risk if they do not.
