MUNICH — US Secretary of State John Kerry said he was preparing to test Russian seriousness about a Syria diplomatic solution after he and Russian Foreign Minister Sergey Lavrov spoke by phone about possible cease-fire arrangements ahead of an International Syria Support Group (ISSG) meeting here; the Feb. 11 meeting comes after Russian-backed Syrian army advances on Aleppo last week collapsed Syria peace talks in Geneva just days after they had begun.
“What we're doing is testing their [Russian and Iranian] seriousness," Kerry said in an interview with The Washington Post. "And if they're not serious, then there has to be consideration of a Plan B. … You can't just sit there."
