Russia moving forces to Ukraine border: UK

"Contrary to their claims, Russia continues to build up military capabilities near Ukraine.

"This includes sightings of additional armoured vehicles, helicopters and a field hospital moving towards Ukraine's borders. Russia has the military mass in place to conduct an invasion of Ukraine."

Earlier, NATO defence ministers said they remained "gravely concerned" by the Russian military build-up and again urged the Kremlin to revert to the "path of diplomacy" in line with its international commitments.

Secretary-General Jens Stoltenberg said NATO was considering establishing new battlegroups in central, eastern and south-eastern Europe to counter the threat from Moscow, which he described as "the new normal".
