There are further indications that Russia continues to concentrate forces along the border with Ukraine, despite assertions from Moscow more than a week ago that many units would be returning to their permanent bases after exercises.
Social media videos geolocated and analyzed by CNN over the past several days show a continuing buildup of armor and support vehicles in two regions: around the Russian city of Belgorod and the town of Valuyki. Both are within 30 kilometers (about 18 miles) of Ukraine’s northeastern border, beyond which lies the major city of Kharkiv, Ukraine.
Dozens of stationary tanks and howitzers — along with other armor — could be observed in fields near Belgorod. Other videos showed a long column of tanks and infantry fighting vehicles parked beside a road between Belgorod and the Ukrainian border.
Some of the formations appear to be considerably larger than those observed last week. Some units have been moving at night, according to videos from the Belgorod area.
In addition, fresh satellite images show that just west of Belgorod, a new field hospital has been constructed at a military site. Southwest of the city, additional troops and equipment are seen in satellite images.
Russian military ambulances and transports have also been identified in areas near the Ukrainian border, as seen in videos posted to social media that CNN has been able to authenticate and geolocate.
In one of the videos, the ambulances are seen stationed in a wooded area near a park in Shebekino, Russia, less than five miles from the Ukrainian border.
Ambulances have also been seen on the move as part of convoys in the Kursk areas, within 50 miles of the border.
New satellite images from Maxar Technologies show that in recent days, additional troops, vehicles and logistics infrastructure have also been deployed to Belarus. At an airfield just southwest of Mazyr, in southern Belarus, dozens of tents and vehicles have appeared in recent days. A satellite image from Feb. 4 shows the area was completely vacant. That airfield is just under 40 kilometers (about 24 miles) from Ukraine’s northern border.
Additionally, social media videos showed a substantial number of attack helicopters in southern Belarus near the city of Gomel. Their current whereabouts are unknown.
Between a week and 10 days ago, there was a flurry of announcements from Moscow, often accompanied by Russian Defense Ministry video that was sometimes contradictory, about units in the vicinity of Ukraine returning to base after exercises. But there have been no further announcements since.
