A human rights commission appointed by President Olusegun Obasanjo has concluded that three of Nigeria's former military rulers were personally liable for extrajudicial killings perpetrated while they were in power. Its report, published on Wednesday after a delay of more than two years, recommended that all three men be banned from holding high office in the future. One of those fingered by the report, General Ibrahim Babangida, is widely believed to be lining up a bid to succeed Obasanjo as elected head of state in the 2007 presidential elections.
