Thousands of men have been detained in filtration camps of Mariupol, facing torture and forced labor; Petro Andriushchenko, adviser to the Mariupol mayor, said on Thursday on Telegram.

Four weeks ago, all men were removed from the Mariupol districts of Guglino, Myrnyi and Volonterivka, he said, with two thousand people being placed in schools and clubs of Bezimyane and Kozatske villages in Novoazovsk district.

These men are forced to sleep on the floors in the corridors with lack of hygiene or access to medical care, he said. According to Andriushchenko, a man died in Kozatske after the Russians refused to call an ambulance. A single sink of cold water is shared by thousands of detainees who receive only porridge as food, he said.

“In the absence of any of the detainees, the occupiers promise to intensify torture and execute other detainees,” he said. Each detainee, including those sick and disabled, is involved in “landscaping work” in the villages, he said.
