On Saturday morning, Ugandans woke to unsettling news of a militant attack on a boarding school in the west of the country. Authorities say 37 students were killed. Five others, including a security guard who tried to stop the violence, also died. The militant Allied Democratic Forces (ADF) are thought to be responsible for the killing. The group originated in Uganda in the 1990s, but now conduct operations from across the border in the Democratic Republic of Congo. So, who exactly are these militants? And what is being done to stop them? #AfricaDaily
