The war in Ukraine has kept everyone’s attention for over eight months now. Many were horrified by the atrocities that accompany war efforts and are ongoing. We see dead soldiers, tortured civilians, sad faces of those who found their relatives killed and happy cries of locals on de-occupied territories. However, not much is known about one of the most marginalised and invisible groups of the population – the prisoners. This text will give you an overview of how prisoners are treated and used in war by both the Ukrainian and Russian state. We are not going to cover the topic of war prisoners (soldiers who were captured by the enemy and placed in special prison) as their conditions of imprisonment and prospects of release depends in many ways on diplomatic relations.
