Ukrainians are being detained and subjected to enforced disappearances in Russian-controlled areas.
United Nations say at least 36 cases of civilian detentions were verified. Ukrainians say they fear an escalating campaign of kidnappings and intimidation, as Russia struggles to assert control over towns it captures.
Viktoriia Roshchyna, a journalist, was working in occupied areas in the east of the country when she was taken by unidentified men last week Tuesday, suspected to be Federal Security Service officers from Russia.
She was released six days later when a video was released and in it, Ms Roshchyna said Russia had not taken her captive and thanked Moscow’s forces for “saving her life’.
