it appears there is SSR coverage, but still I doubt it would be utilized operationally. The squawk 2000 hints to this assumption, too. However there is no mentioning of the radar installation in the AiP.
My info os that Thales has a contract with AECNA ( the multinational ATS service provider over Burkina Fasso) to install a MSSR in Ouaga , installed but not operational yet. What we saw is maybe just a replay from an engineering control screen , not the operational one.
