Since August 2015, the security forces have killed at least 150 members and supporters of the pro-Biafran organization IPOB (Indigenous People of Biafra) and injured hundreds during non-violent meetings, marches and other gatherings. This report focuses on the crisis brewing in the southeast of Nigeria, where IPOB campaigns for an independent state of Biafra. It documents extrajudicial executions and the use of excessive force by military, police and other security agencies. It also shows a worrying pattern of arbitrary arrests and detentions, including soldiers arresting wounded victims in hospital, and of torture and other ill-treatment of detainees.
