Russia has said talkswith Nato on the Ukraine crisis had reached a ‘‘dead end’’, escalating fears of an imminent invasion. High-stakes talks betweenMoscowand theWest have been taking place across Europe this week in a bid to find a solution to the crisis, amid a 100,000-strong build-up of Russian troops along the Ukrainian border. Sergey Ryabkov, Russia’s deputy foreign minister and a lead negotiator in the talks, said the meetings had reached a ‘‘dead end of sorts’’. Moscowwould not continue discussing ‘‘secondary’’ security issues if the Westwas deaf to the country’s more pressing security concerns, he said.
