at a makeshift base near the border with Ukraine, a Reuters reporter saw this week.
Many of the vehicles have number plates and identifying marks removed while many of the servicemen had taken insignia off their fatigues. As such, they match the appearance of some of the forces spotted in eastern Ukraine, which Kiev and its Western allies allege are covert Russian detachments.
The scene at the base on the Kuzminsky firing range, around 50 km (30 miles) from the border, offers some of the clearest evidence to date of what appeared to be a concerted Russian military build-up in the area.
Earlier this month, NATO military commander General Philip Breedlove said he believed the separatists were taking advantage of a ceasefire that came into force in February to re-arm and prepare for a new offensive. However, he gave no specifics.
Russia denies that its military is involved in the conflict in Ukraine’s east, where Moscow-backed separatists have been fighting forces loyal to the pro-Western government in Kiev.
Russia’s defense ministry said it had no immediate comment about the build-up. Several soldiers said they had been sent to the base for simple military exercises, suggesting their presence was unconnected to the situation in Ukraine.
