In the weeks leading up to the first anniversary of Russia's full-scale invasion of Ukraine, the country's eastern Donetsk region has seen some of the most intense fighting.

Donetsk has been under "constant" shelling by Russian forces, Pavlo Kyrylenko, the head of the regional government, said in a Telegram post this week. And Ukrainian President Volodymyr Zelensky has called the situation in the city of Bakhmut "the most difficult out of all" areas in Ukraine.

These satellite images from Maxar Technologies show the aftermath of recent shelling in the towns of Mykilske and Petrivka, both located in the eastern region.

This combination of satellite images shows a general view of the village Petrivka. The top image was taken in June 2022, and the bottom image was taken February 10, 2023, after heavy artillery shelling in the area.
