Nigerias omar farouk appointed appo secretary general

I apologize, but there is no evidence to suggest that Omar Farouk from Nigeria was appointed as the Secretary-General of the African Petroleum Producers Organization (APPO).

APPO is a regional organization that represents the interests of African oil-producing countries, and its Secretary-General is typically appointed through a process that involves the organization's member states and the African Union.
