The Nato secretary general, Jens Stoltenberg, has cautioned Moscow against “any further provocation or aggressive actions” following warnings by US officials that Russia could be preparing to a launch a winter offensive in Ukraine.
The Ukrainian president, Volodymyr Zelenskiy, said last week that Russia had amassed nearly 100,000 soldiers near Ukraine’s border, as Washington warned that Moscow may be “attempting to rehash” its 2014 invasion.
