Dramatic satellite images released by Maxar Technologies on Monday evening showed a massive 40+ mile long convoy of Russian military vehicles snaking along roadways northwest of Kyiv. 

It’s easy to trace where those hundreds of tanks, towed artillery, armored and logistical vehicles came from. Just follow the roads.

In Ukraine, northwest of Kyiv, all roads lead to Belarus. The roadway and bridge at Chernobyl — the town, not the failed nuclear reactor — ends in Belarus. Every other major road northwest of the Ukrainian capital, Kyiv, ends in Belarus, which borders northern Ukraine.

Russian buildup of troops: For weeks prior to its invasion of Ukraine, Russia amassed its forces in Belarus.

Hundreds of Russian military vehicles, aircraft and helicopters were moved to the former Soviet state in order to participate in what the two allies described as joint exercises. But after the maneuvers ended, the Russian forces didn’t go home.

In fact, additional satellite imagery from Maxar showed that Russia continued to increase the amount of military vehicles, air power and weaponry in Belarus. From the city of Brest in the country's east, to Gomel in the west, Russian forces kept popping up at air bases, in towns and in even in fields on satellite images and social media.

Pontoon bridge: Satellite images even showed that Russia constructed a pontoon bridge across the Pripyat River in the greater Chernobyl exclusion zone, which spans Ukraine and Belarus. The day the invasion into Ukraine began, additional satellite images from Capella Space showed Russia began moving dozens of military vehicles across that bridge.

Military power: The sheer length of the convoy is massive and speaks to the amount of the military power the Russians have amassed to try and take Kyiv.

It also speaks to Belarus’ activity in supporting and carrying the invasion — and responsibility for it.

That military power could not have been amassed by the Russians without the permission, and assistance, of Belarus.
