Russia has condemned a US decision to send extra troops to Europe to support its Nato allies amid continuing fears of a Russian invasion of Ukraine.
Moscow said it was a “destructive” step that heightened tension and reduced the scope for a political solution.
The Pentagon said 2,000 US troops would be sent from North Carolina to Poland and Germany, and a further 1,000 already in Germany would go to Romania.
Russia has some 100,000 troops near Ukraine. It denies planning to invade.
The tensions come eight years after Russia annexed Ukraine’s southern Crimea peninsula and backed a bloody rebellion in the eastern Donbas region.
Moscow accuses the Ukrainian government of failing to implement the Minsk agreement – an international deal to restore peace to the east, where Russian-backed rebels control swathes of territory and at least 14,000 people have been killed since 2014.
