The US is heaping new pressure on Russia to change course and support international action in Syria, warning that intransigence by Moscow may lead to open civil war that could spill across the Middle East with devastating consequences, - AP reported.
Speaking in Denmark, US secretary of state Hillary Clinton slammed the Russian government for continuing to support Syrian president Bashar Assad, even after last week's massacre of more than 100 people in the town of Houla.
She said Russia's position "is going to help contribute to a civil war" and rejected Russian officials' insistence that their stance actually is helping to ease the crisis.
On the first stop of a European tour, Mrs Clinton said Russia and China would have to be on board before the US and other nations might engage in what could become a protracted conflict in support of a disorganised rebel force.
Russia, along with China, has twice vetoed UN Security Council sanctions against Syria. Russia is Syria's closest ally other than isolated Iran, and Mrs Clinton said that without its support the international community is essentially frozen from taking concrete steps to end the violence.
"The Russians keep telling us they want to do everything they can to avoid a civil war because they believe that the violence would be catastrophic," Mrs Clinton said, noting that they are "vociferous in their claim that they are providing a stabilising influence".
But she said: "I reject that," complaining that in fact Russia is propping up Mr Assad as his government continues a brutal, 15-month crackdown on dissent in which some 13,000 people have died.
The Obama administration has called on Assad to step down and clear the way for a political transition. But mindful of a war-weary American public, it has stopped short of advocating direct US military engagement in the country and stressed the need for diplomacy, particularly with Moscow, which continues to sell weapons and provide political support to Assad.
In Washington, despite revulsion over the Houla massacre, officials said the administration remains deeply concerned about the possible consequences of military action. But as the violence continues, they acknowledge that planning for some sort of intervention is under way.
Two Western diplomats told journalists that top US and British commanders and intelligence officers visited the northern Jordanian city of Ramtha recently and toured the area along the Jordan-Syria border to assess the possibility of a limited land attack. But it was decided that air attacks would be best, considering the mostly bushy terrain and climate conditions, the diplomats said.
