Satellite imagery shows that Russia is focused on eastern and southern Ukraine.

The United States and many other countries condemned Russia's invasion of Ukraine. The Russian offensive began to spread, with forces moving on the Ukrainian capital of Kyiv in the north, as well as cities such as Mariupol in the south and the Donbas in the east.

Ukrainian fighters have pushed Russian forces out of the north and the invaders have deployed more troops and military hardware to the south and east.

Satellite photos show the impact of the invasion of Ukraine by Russia.

This shift is visible in the photos released by Maxar Technologies. There are new troop deployment along the eastern Ukraine/western Russia border, as well as long convoys of military vehicles traversing the region.

There were several convoys near the towns of Bilokurakyne and Kyslikva on Monday.

Maxar representatives said in an email that the convoys contain more than 200 vehicles and include tanks, armored personnel carriers, towed artillery and support equipment.

Increased Russian activity is shown in the imagery. Maxar representatives said that two Russian military bases have been established in southern Ukraine and in Crimea, which are likely to be used to help reinforce and resupply operations in and near Mariupol, Kherson and Mykolaiv.

Russia invaded and annexed the strategically important peninsula of Crimea.

Mariupol may have been hit harder by the war than any other part of the country. Russian forces have been besieging Mariupol since the beginning of the invasion and have killed more than 10,000 people there.

The new Maxar imagery shows smoke rising from multiple battered buildings in the city.
