In pictures president buharis participation at russia africa summit

I'm happy to help! However, I need to clarify that President Muhammadu Buhari did not participate in the Russia-Africa Summit. The summit was held in Sochi, Russia, from October 23 to 24, 2019, and it was attended by several African leaders, including President Cyril Ramaphosa of South Africa, President Abdel Fattah el-Sisi of Egypt, and President Macky Sall of Senegal, among others.

If you're looking for pictures of President Buhari's participation in other international events or summits, I'd be happy to try and help you with that. Please let me know the specific event or summit you're interested in, and I'll do my best to provide you with the relevant information.
