The top U.S. and Russian diplomats made no major breakthrough at talks on Ukraine on Friday but agreed to keep talking to try to resolve a crisis that has stoked fears of a military conflict.
After the talks in Geneva, U.S. Secretary of State Antony Blinken warned of a "swift, severe" response if Russia invades Ukraine after massing troops near its border. Russian Foreign Minister Sergei Lavrov said Moscow was still waiting for a written response to its demands for security guarantees.
