Taken together, a picture emerges of a brutal and systemic assault on Ukrainian prisoners. Satellite imagery shows that as the prison filled up with Ukrainians, during the summer of 2022 it was reinforced with new steel roofs. The first Ukrainian prisoners were sent there in April 2022, often tied up and blindfolded onboard military trucks daubed with the Z symbol. All Ukrainian prisoners who passed through Taganrog reported horrifying and sustained torture, including civilians and female prisoners. The information suggests Ukrainian detainees have been scattered across Russia, held as far as 600 miles from the border with Ukraine.
