The US embassy has warned American citizens in Ukraine about a rally the far-right National Corps plans to hold in central Kyiv on 16 March.
"This group has been linked to violence and public disorder, including clashes with police. Large crowds are expected in the area," it said.
The embassy advised US citizens to avoid crowds and demonstrations, expect heavier than normal police presence; expect street closures, restrictions, and searches; be aware of your surroundings; follow local law enforcement instructions, and monitor local media for updates.
