Satellite images made it possible to reproduce the filtration system in the occupied territories

Researchers from the Yale School of Public Health conducted an investigation into the filtration of the Ukrainian population by the occupiers in the Donetsk region. With the help of satellite images, they have established 21 objects in which citizens of Ukraine are being held.

Satellite images

Specialists from the Laboratory of Humanitarian Studies of the Yale School of Public Health conducted a comprehensive study of satellite images of the Russian-occupied areas of Donetsk region. They found 21 objects that are components of the population filtration system created by the Russians.

By combining satellite images with data from open sources, the researchers found that the objects can be intended for four different purposes. Some of them are intended for filtering, others for registration, detention or punishment of Ukrainians. Also, institutions can perform several functions at the same time.

There is evidence that the system was created a few weeks before the start of a large-scale invasion and was expanded after the capture of Mariupol. Individual filtration objects are clearly visible already on satellite images taken in March.

Investigation into the murder of prisoners

The researchers paid special attention to correctional colony No. 120 near Olenivka. The invaders turned it into a prison camp. And already the pictures taken at the end of March-beginning of April demonstrate suspiciously large-scale excavations of the ground near the wall of this institution. Following the example of Bucha, experts know that they can be a sign of mass burial.

The researchers also drew attention to the rows of graves that appeared near the colony in July 2022 and are shown in two series of images taken on July 18 and 27. They appeared there right before the missile attack, in which several dozen Ukrainian prisoners of war were allegedly killed.

The investigators insist that they have all the evidence that the prisoners of war are in terrible sanitary conditions, and satellite images indicate the need for access to the graves of independent investigators, but Russia still refuses to grant them appropriate access.
