Ukraine-Russia tensions: Russia pulls some troops back from border

Russia says it is pulling back some of its troops from near Ukraine after a build-up raised fears of an invasion.

The defence ministry said that large-scale drills continued but that some units were returning to their bases.

There has been no independent confirmation of the withdrawal and international powers have reacted cautiously to the announcement.

More than 100,000 Russian troops have massed at Ukraine's border. Russia has always denied it is planning an attack.
