UKRAINE BARS RUSSIAN MEN AGES 16-60 FROM ENTERING THE COUNTRY: It’s war in Europe.

Martial law has been imposed in 10 Ukrainian regions until 26 December.

The move came as Ukraine’s president expressed fears of a Russian invasion after Russian forces seized three Ukrainian boats and 24 sailors.

Ukraine said Sunday’s incident in the Black Sea was a flagrant violation of international law, while Russia says the vessels violated its territorial waters.

The Kerch Strait incident is very serious.
