Yes, it is true that the British had concentration camps in Kenya from 1952 to 1960 during the Mau Mau Uprising. The British colonial authorities set up these camps to intern and detain suspected Mau Mau rebels and their supporters. The camps were overcrowded and unsanitary, and the detainees were subjected to torture, rape, and other abuses.
The British government has never acknowledged or apologized for the abuses that took place in the concentration camps. However, in 2013, the Kenyan government opened a Truth, Justice, and Reconciliation Commission to investigate the abuses. The commission found that the British colonial authorities had committed crimes against humanity in the concentration camps.
The estimated number of people who died in the concentration camps is between 100,000 and 300,000. The British government has never compensated the victims or their families for the abuses that took place.
The Mau Mau Uprising was a guerrilla war waged by the Kikuyu people of Kenya against British colonial rule. The war lasted from 1952 to 1960 and resulted in the deaths of thousands of people. The British government eventually suppressed the uprising, but the abuses that took place in the concentration camps have left a lasting legacy of pain and suffering.
