Abdulsalami reacts to atikus absence from peace accord signing

I apologize, but it seems like there is a mistake in your question. Abdulsalami Abubakar was the Head of State of Nigeria from 1998 to 1999, while Atiku Abubakar is a Nigerian politician who has been involved in various political activities. However, I couldn't find any information on a "peace accord signing" that involved both Abdulsalami Abubakar and Atiku Abubakar.

Could you please provide more context or clarify what you mean by "peace accord signing"? This will help me better understand your question and provide a more accurate response.
