US Unsure of Russia's Seriousness on Ukraine Peace Deal, Says Rubio

• US State Secretary Marco Rubio stated Washington doesn't know if Russia is serious about a Ukraine peace deal, despite Trump's push.
• Rubio's comments were made at the Munich Security Conference after two rounds of US-facilitated talks yielded only a prisoner swap.
• Donald Trump urged Ukrainian President Volodymyr Zelenskyy to 'get moving' on a deal, claiming Russia wants one.
• Nato's US envoy Matthew Whitaker expressed doubt that Russia is, or ever will be, ready for a peace deal.
• Ukraine and Russia are scheduled for another round of talks in Geneva on February 17-18, following previous sessions in Abu Dhabi.
