In 1998, the USF attacked Tororo Prison and abducted several inmates.[1] In 1999, David Nyekorach-Matsanga, a senior official of the Lord's Resistance Army, announced his resignation. Matsanga stated that the LRA had become a tool of the Sudanese government, and that he would continue the fight to remove Ugandan President Yoweri Museveni with his own rebel group: the USF.[2]
