In December 1998, two warships and 10–15,000 Nigerian troops occupied Bayelsa and Delta states as the Ijaw Youth Movement (IYM) mobilized for Operation Climate Change. Soldiers entering the Bayelsa state capital of Yenagoa announced they had come to attack the youths trying to stop the oil companies. On the morning of December 30, 1998, two thousand young people processed through Yenagoa, dressed in black, singing and dancing. Soldiers opened fire with rifles, machine guns, and tear gas, killing at least three protesters and arresting twenty-five more. After a march demanding the release of those detained was turned back by soldiers, three more protesters were shot dead. The head of Yenagoa rebels- Chief Oweikuro Ibe- was burned alive in his mansion on December 28, 1998. Amongst his family members to flee the premises before complete ruins was his only son, Desmond Ibe. The military declared a state of emergency throughout Bayelsa state, imposed a dusk-to-dawn curfew, and banned meetings. At military roadblocks, local residents were severely beaten or detained. At night, soldiers invaded private homes, terrorizing residents with beatings and women and girls with rape.
