Russian Foreign Minister Sergei Lavrov and U.S. Secretary of State Anthony Blinken are in Geneva to discuss soaring tensions over Ukraine. Both sides struck a pessimistic tone as proceedings got underway. The talks come after a string of meetings over the last week failed to reach common ground. Russia has massed tens of thousands of troops on its borders with Ukraine, and Western states fear Moscow is planning to invade its neighbor. The Kremlin has denied this, but has indicated it could take unspecified military action if a list of demands given to the U.S. and NATO are not met.
