An anti-corruption group says Africa is the most corrupt region in the world, with Somalia being the most corrupt country.
Transparency International released its annual report Tuesday surveying perceived corruption in 178 countries.
The 2010 list ranks six African nations among the 10 most corrupt countries. They are Somalia, Sudan, Chad, Burundi, Angola and Equatorial Guinea.
Transparency International scores countries on a 10-point scale, with zero being the most corrupt. Forty-four of the 47 African nations scored less than five on the index, meaning they have serious levels of corruption.
The Berlin-based group ranked Botswana as the least corrupt African country, with a score of 5.8.
The report defines corruption as the "abuse of entrusted power for private gain," in public and private sectors. It scores countries based on assessments of the prevalence of bribery of public officials, embezzlement of public funds, kickbacks in public procurement, and questions about the effectiveness of public anti-corruption efforts.
