Satellites over Eastern Europe have shown a colossal convoy of Russian tanks and military vehicles snaking towards the Ukrainian capital earlier this week.

The images, taken by Maxar Technologies on the morning of Monday February 28, show a vast Russian military convoy north of the besieged Ukrainian capital of Kyiv. They initially reported that the convoy of heavy metal trailed more than 27 kilometers (17 miles), but they later revised this to say it stretches down much of a 64 kilometer (40 mile) road long between Antonov airport and Prybirsk.

They also note that a number of homes and buildings can be seen set alight north and northwest of Ivankiv, not far from the path of the convoy.

Maxar’s eyes in the sky also detail military activity in southern Belarus, a strong Russian ally that borders Ukraine. 

Ground forces field deployments are seen near Khilchika, approximately 12 kilometers (8 miles) north of the border with Ukraine, and Teshkov, approximately 19 kilometers (12 miles) away from the border. Meanwhile, less than 32 kilometers (20 miles) north of the border with Ukraine, Maxar Technologies notes the presence of both ground forces deployments and ground attack helicopter units.

Ukrainian authorities claimed Belarusian troops were on Ukrainian soil on Tuesday March 1. While this has yet to be confirmed by other sources, it’s clear Belarus has played an important role in the Russian invasion of Ukraine and the US believes they will send troops there soon, perhaps as early as this week.
