Russia-Ukraine border: Nato warning over military build-up

The head of Nato has urged Russia to be transparent about its military plans after an increase in the numbers of troops on its border with Ukraine.

Jens Stoltenberg said a “large and unusual” build-up of Russian forces had been spotted on the border in recent weeks.

He spoke amid speculation Russia could be planning to invade Ukraine.

Moscow has dismissed such fears as “alarmist” and complained of increasing Nato activities in the region.
