Belarus has huge numbers of political prisoners - around three times as many as in Russia, in a far smaller country.

Almost industrial scale arrests began after huge, peaceful pro-democracy demonstrations swept the country in 2020 after Alexander Lukashenko claimed a landslide victory in presidential elections. Mr Lukashenko has been in power for 30 years. Protestors said the result was a fraud, and that they’d been cheated of their vote.

Almost four years on, the authorities are still making mass arrests.

Many of those detained are women. The most prominent woman prisoner, Maria Kolesnikova, a professional flute player, has been incommunicado for over a year, with no word at all reaching her family or lawyers.

Political prisoners are made to wear a yellow patch on their clothes. The women say they kept short of food and made to sew uniforms for the security forces, to clean the prison yard with rags and shovel snow. They speak of undergoing humiliating punishments such as standing in parade grounds under the sun for hours.

Yet they also tell us of camaraderie and warmth in their tiny cells as they try to keep one other going. And women on the outside continue to take personal risks to help the prisoners by sending in food, warm clothes and letters.
