Secretary of State Anthony Blinken is in Switzerland meeting with Russian officials to discuss the tension along the Russian-Ukrainian border.
Secretary of State Anthony Blinken says he's met with his Russian counterpart to keep dialogue open over the Ukraine.
Russian troops have amassed along the Ukrainian border over the last several months in what Moscow has described as military exercises, but Ukraine and others view it as a possible invasion.
Blinken says he has communicated that NATO and her allies will take "swift, severe, united response" to aggression taken by Russia.
Blinken says what they will not go back on is the fundamental principles they've committed to defend.
