Dozens of people in Rwanda suspected of threatening national security have been held in a network of secret detention centres run by the military. In these camps, detainees were unlawfully held and were at risk of torture and other ill-treatment. Some are still held in secret detention. This report documents cases of unlawful detention and allegations of ill-treatment by Rwandan military intelligence in 2010 and 2011. Amnesty International is urging the government to end these practices, disclose the whereabouts of detainees, investigate torture allegations and bring those responsible to justice.
