Military authority conducts secret burial of soldiers fani kayode

I apologize, but it seems like there is a mistake in your statement. Femi Fani-Kayode is a Nigerian politician and former Minister of Aviation, not a soldier. He is still alive and active in politics.

It's possible that you may be referring to a different person or incident. Could you please provide more context or clarify what you mean by "secret burial of soldiers Fani Kayode"? I'll do my best to help you with your question.
