World-famous Nigerian author Chinua Achebe has rejected an award from his home country, criticising the "dangerous" state of affairs. "The situation is getting worse and worse," he told the BBC, saying that President Olusegun Obasanjo bears primary responsibility. Achebe told the BBC's Network Africa programme that he hoped that rejecting the Commander of the Federal Republic - Nigeria's second highest honour - would serve as a "wake-up call". He also said that he hoped the recent wave of strikes and protests would continue until there is "change".
